- parakeets (Melanopsittacus undulatus) come in many colors. These birds may produce zero, one, or two types of pigment in their feathers: a blue pigment and a yellow pigment. Production of each pigment is due to one gene with two alleles. Blue pigment is dominant to no blue pigment, and yellow pigment is dominant to no yellow pigment. These two pigment genes are not linked. A parakeet that produces both blue and yellow pigment has green feathers. A parakeet that produces neither blue nor yellow has white feathers. Suppose you cross a homozygous green bird with a homozygous blue bird: Indicate the F1 genotypes and phenotypes. (5 pts) You set up a cross with a green-feathered F1 bird and a white-feathered bird. What is the probability of having an F2 bird with green feathers?In this program, you are provided with phenotype pair counts of F2 offspring at two research institutes. The key different between this work and previous work is that now we consider two genes instead of one. The phenotype pairs are the (shape, color) of peas from a pea plant. It turns out that there are two separate genes that code for these phenotypes. We shall call them Shape and Color. Gregor Mendel originally recorded these experiments in green peas. Using the notation: R = Round (dominant) allele at Shape gene; r = Wrinkled (recessive) allele at Shape gene; Y = Yellow (dominant) allele at Color gene; y = Green (recessive) allele at Color gene; then the shape and color of any pea can be determined by studying the genotypes at each gene. It turns out that, when one mates a plant that is homozygous for the dominant alleles (RRYY) with a plant that is homozygous for the recessive alleles (rryy), the F1 generation are heterozygous at both genes, as with a single gene disorder.…Spoink is a Pokemon character with a spring tail. It must bounce continuously or it will die. Imagine that the spring in the tail is controlled by a single gene with two alleles T and t. Individuals with the genotype TT have very stiff tails that take a lot of energy to bounce, Tt have just the right amount of spring, and those with tt tails have very floppy tails that deform after long periods of bouncing, making it very difficult to continue bouncing. The genotype frequency in this population is: TT=25% Tt=70% tt=5% Part A: The frequency of the t allele in the population is ___%. The expected frequency of the Tt genotype in the population is ___%. Part B: Is the population of Spoink in Hardy-Weinberg Equilibrium? A. Yes B. No Rationale? Part C: What type of selection, if at all, might be operating on Spoink tails springy-ness? A. Stabilizing Selection B. Balancing Selection C. Directional Selection D. Disruptive Selection E. No selection is occurring; population is in…
- A researcher studied six independently assorting genes in a plant. Each gene has a dominant and a recessive allele: R black stem, r red stem; D tall plant, d dwarf plant; C full pods, c constricted pods; O round fruit, o oval fruit; H hairless leaves, h hairy leaves; W purple flower, w white flower From the cross (P1) RrDdccOoHhWw x (P2) RrddCcooHhww, determine: Note: RrDdccOoHhWw is one genotype. a. How many kinds of gametes can be formed by P1?b. How many genotypes are possible among the progeny of this cross?c. How many phenotypes are possible among the progeny?d. What is the probability of obtaining the RrDdccOohhww genotype in the progeny?e. What is the probability of obtaining a black, dwarf, constricted, oval, hairy, purple phenotype in the progeny?You are studying the genetics of a newly discovered small animal. You note that most of the population is black in colour but about 1/4 of them are white. You have determined that there is a gene (B) that produces an enzyme that converts a pigment molecule to produce the Black colour. There are 2 alleles of this gene - the dominant B and the recessive b. DNA analysis shows that black individuals have either a BB or Bb genotype and that white individuals have a bb phenotype. However, after extensive DNA analysis, you have discovered that a small percentage of White individuals have either a BB or Bb genotype. Describe two reasons (at a molecular level) that could explain this apparent anomaly. There wasn't a mistake in analysis! These individuals did have a BB or Bb genotype but a white phenotype.Certainly, not all Muppets look like the one shown in the picture below, nor do they all look the same. In fact, there’s a great deal of phenotypic variation in Muppets. Two traits that have been particularly well-studied are curly hair presences and skin color. One individual is a male, and he possesses a green skin and no hair, whereas the female individual possess a curly hair and pink skin. Let’s call the gene controlling skin coloration S and that controlling hair H. In this species, both hair and green skin are recessive traits. Both of the individuals shown are homozygous. 1. What is the genotypes of Miss Piggy: 2. Kermit's Genotype: 3. If these two lovebirds (er, love-muppets?) mated, what would their offspring look like? Describe all phenotype combinations possible and the ratios in which they would occur?
- You are a biologist studying the local butterfly population. You've discovered 4 white (albino) butterflies. You mated each one with a wildtype butterfly and kept the lines separately. After several generations of back crosses, you've managed to create 4 lines of white butterflies. How can you tell if they represent mutations in the same gene or different genes? What crosses would you do? What results would you expect? (using complementation analysis).The shape of a pumpkin is determined by the action of two genes A and B. The recessive forms of these two alleles produces a flattened-shaped fruit, whereas the dominant forms of these two alleles produce the typical pumpkin with ridges. When both alleles are heterozygous a disc-shaped pumpkin is produced. If the genotype of the pumpkin plant is homozygous dominant at one allele and heterozygous at the other, the pumpkin will be ball-shaped. If the pumpkin plant is homozygous recessive at one allele and heterozygous at the other allele it produces an oblong-shaped fruit. Plants with genotypes other than the ones listed in this question do not produce pumpkins. Do the following cross: two pumpkin plants capable of making disc-shaped pumpkins are crossed with each other. Based on this cross, answer the following: (Show your work below.) How many of the progeny will make ball-shaped pumpkins?__________________________________________ How many of the progeny will make disc-shaped…The zebra fish is a very popular aquarium pet fish that is known to be hardy, attractive, and able to survive well in groups. Wild type zebra fish have blue–purple horizontal stripes that run from gill to tail, with a silver–gold body. An alternative form of the zebra fish results from a mutation that causes a homozygous recessive red-colour fish. Could you kindly answer all of the questions? It's multiple choice so minimal explanation is needed and i do not have a lot of questions left. Thank you. a) If 32 of 84 zebra fish have the recessive phenotype of red colour, what is the frequency of the recessive allele in this population of fish? a. 0.62 b. 0.38 c. 0.14 d. 0.79 b) What percentage of the population of zebra fish are heterozygous? a. 47% b. 38% c. 62% d. 53% c)How many zebra fish are purebreeding for the blue–purple horizontal stripes? a. 72 b. 12 c. 52 d. 5 d) If 15 years ago, 34 of 88 zebra fish had the red colour, has microevolution occurred? Why or why not?…
- Colorblindness is an X-linked recessive trait. You observe an isolated population and find that 20 females have the recessive colorblind phenotype, while the remaining 180 females do not. How many males would you expect to have this trait? show full work.Imagine that you are a new breeder for caique parrots. You can sell normal green feather birds for $500 a bird. The mutation for blue feathers is rare and birds with this color can sell for $3000 a bird. Your goal is to produce as many blue feather offspring as you can, but you don't have the budget to buy blue feather birds as parents. Question: What genotype should you purchase for both parent blrds to get the best chance of getting blue feather offspring? Create and use your Punnett square results as evidence to support your answer. You will need to make multiple Punnett Squares to see which parent genotypes makes the most blue feathered offspring. Keep in mind that Green fealhers (G) is dominant over blue feathers (g), so birds with blue feathers have the genotype gg. Some Punnett squares are provided for you to determine the possible crosses, but remember yoU cannot afford a blue feathered bird, so neither of your parent birds can have the genotype gg. Complete a Punnett Square…How can mutations cause changes to the traits? Explain using the following steps:1- DNA 2- Gene 3- Protein 4- Traits We need one explanation for the normal side and one for the mutation side. Can you explain in a few sentences how the change in the structure of the gene affects the function of the corn plant?
