Most of the individuals of a certain wildflower population have white flowers, although a few are purple-flowered. Crosses have demonstrated that allele for white color flower (W) is dominant over the allele for purple (w). Give the genotype of a purple-flowered plant, and show the gametes that it would produce as a result of meiosis. If two heterozygous whoite-flowered plants are crossed. What fraction of the offspring do you expect to be purple? If two purple-flowered plants are crossed, what fraction of their offspring do you expect to be white?

Most of the individuals of a certain wildflower population have white flowers, although a few are purple-flowered. Crosses have demonstrated that the allele for white color flower (W) is dominant over the allele for purple (w). Give the genotype of a purple-flowered plant, and show the gametes that it would produce as a result of meiosis. If two heterozygous white-flowered plants are crossed. What fraction of the offspring do you expect to be purple? If two purple-flowered plants are crossed, what fraction of their offspring do you expect to be white?
Given the following information, determine the inheritance of flower color in this plant and determine the genotypes of the parental individuals, which are from pure- breeding lines. CROSS 1 CROSS 2 purple X colorless all purple 9/16 purple colorless X red all purple as in Cross 1 F1 F1 F2 F2 3/16 red 4/16 colorless
An individual that is homozygous AABBcc is crossed to an individual that is homozygous aabbCC producing F1 individuals with genotype AaBbCc. Assume that the A, B, and C loci are all on the same chromosome. One chromatid at the start of meiosis (before crossing over) has the alleles A, B, and c. What alleles are on its sister chromatid? What alleles are on the homolog? Group of answer choices A. Sister chromatid ABc, Homolog no way to tell B. Sister chromatid ABC, Homolog abc C. Sister chromatid ABc, Homolog abC D. Sister chromatid abC, Homolog ABc
The crossing of two orange-flowering plants results in ~2/3 orange-flower progeny and ~1/3 white-flower progeny. The crossing of two orange-flowering F1 plants generates the same progeny ratios as observed for the parental cross, while the crossing of white-flowering F1 plants only produces white-flowering progeny. What is a likely explanation for these results?
A farmer crossed a tall (T) pea plant carrying yellow seeds and a dwarf pea plant (t) carrying green seeds . Tall is dominant over the dwarf and yellow is dominant over the green. Fertilization of the first generation pea plants produced a total of 16 second filial generation offsprings of the pea plants. How many tall pea plants that will have green seeds can you expect to be produced? What will be the genotype of these plants (Homozygous? Heterozygous? Or Both?).
In the following cross, imagine that you have a female fly that has two Xs and one Y due to a nondisjunction event in her mother's germ cells. Draw out what the possible gametes are for both the female and the male and also a Punnett square showing the genotypes, phenotypes, and sex of the possible flies as a result of this cross. You do not need to provide the probabilities of each of these. Red-eyed wi C Ở Red-eyed wt XX Y X Y Meiosis
Two plants in a cross were each heterozygous for two gene pairs (AB/ab) whose loci are linked and 10 map units (mu) apart. (Recall that 1 mu is equal to 1% recombination between two genes.) Assuming that crossing over occurs during the formation of both male and female gametes and that the A and B alleles are dominant, determine the phenotypic ratio of their offspring. Part D If the two genes are 15 mu apart and the plant is (Ab/aB), what proportion of gametes from a signal plant will be ab? Part E What proportion of the offspring of two plants ( both (Ab/aB)) will be A_B_ if the genes are 15 mu apart? Part F What proportion of the offspring of two plants ( both (Ab/aB)) will be A_bb if the genes are 15 mu apart? Part G What proportion of the offspring of two plants ( both (Ab/aB)) will be aaB_ if the genes are 15 mu apart? Part H What proportion of the offspring of two plants ( both (Ab/aB)) will be aabb if the genes are 15 mu apart? How would I solve these?
The crossing of two orange-flowering plants results in 61 orange-flower progeny and 27 white-flower progeny. The crossing of two orange-flowering F1 plants generates a similar progeny ratio as observed for the parental cross, while the crossing of white-flowering F1 plants only produces white-flowering progeny. What is a likely explanation for these results?
Two plants in a cross were each heterozygous for two gene pairs (AB /ab) whose loci are linked and 30 map units (mu) apart. (Recall that 1 mu is equal to 1% recombination between two genes.) Assuming that crossing over occurs during the formation of both male and female gametes and that the A and B alleles are dominant, determine the phenotypic ratio of their offspring. Part E: What proportion of the offspring of two plants (both (AB/ab ) will be A - B- if the genes are 30 mu apart? Part F: What proportion of the offspring of two plants (both (AB/ab)) will be A - bb if the genes are 30 mu apart? Part G: What proportion of the offspring of two plants (both (AB/ab)) will be aaB- If the genes are 30 mu apart? Part H: What proportion of the offspring of two plants (both (AB/ab)) will be aabb if the genes are 30 mu apart?
In currant moths, their Light color is sex-linked and recessive (d) to dark color (D). What are the phenotypes and genotypes of the parents if a certain cross yields ½ dark and ½ light colored females and all dark males? Female moths are heterogametic. Show COMPLETE cross.
In garden peas, yellow seeds (Y) are dominant to green seeds (y), and inflated pods (I) are dominant to constricted pods (i). Suppose you have crossed YYII parents with yyii parents. Draw the F1 Punnett square and predict the expected F1 phenotype(s). List the genotype(s) of gametes produced by F1 individuals. Draw the F2 Punnett square. Based on this Punnett square, predict the expected phenotype(s) in the F2 generation and the expected frequency of each phenotype.
In onion, male sterility is produced when the nuclear genotype is aa and the mitochondrial gene S (sterile) are present. Any other combination of nuclear genotype and mitochondrial gene (including gene F for fertile) will result in a male fertile plant. Give the genotypic ratio and the phenotypic ratio or the percentage of male sterile and male fertile offspring that will be produced in the following crosses. 1. Aa + S male x aa + F female 2. Reciprocal cross of number 1. (Note that when we do reciprocal cross, we interchange/swap the genotypes of the parents (if there is a nuclear gene involved, you interchange the nuclear genotype as well). 3. Aa + S female x Aa + F male 4. Reciprocal cross of number 3.
