If you crossed a homozygous round, heterozygous yellow plant with a heterozygous round, white plant, what are the genotypes of the plants involved in this cross? Answer RRYY X rryy?

In a particular plant, two genes control leaf shape and color. Round leaves (R) are dominant to jagged leaves (r). Yellow fruits (Y) are dominant to white fruits (y). If you crossed a homozygous round, heterozygous yellow plant with a heterozygous round, white plant, what are the genotypes of the plants involved in this cross?

In watermelons, bitter fruit (B) is dominant over sweet fruit (b), and yellow spots (S) are dominant over no spots (s). The genes for these two characteristics assort independently. A homozygous plant that has bitter fruit and yellow spots is crossed with a homozygous plant that has sweet fruit and no spots. The F1 are intercrossed to produce the F2. What will be the phenotypic ratios in the F2? 2. If an F1 plant is backcrossed with the bitter, yellow-spotted parent, what phenotypes and proportions are expected in the offspring? 3. If an F1 plant is backcrossed with the sweet, non-spotted parent, what phenotypes and proportions are expected in the offspring? 4. In cats, curled ears (Cu) result from an allele that is dominant over an allele for normal ears (cu). Black color results from an independently assorting allele (G) that is dominant over an allele for gray (g). A gray cat homozygous for curled ears is mated with a homozygous black cat with normal ears. All the F1…
You have a purple-flowered pea plant, but you do not know if it is homozygous (PP) or heterozygous (Pp) for flower color because both genotypes result in the same purple phenotype. Purple color allel (P) is dominant over white flower allel (p). What would you do to determine the genotype of flower color of this plant? Lötfen birini seçin: O a. Crossing the plant with homozygous large flowered pea plant (LL) Ob. Crossing the plant with heterozygous purple flowered pea plant (Pp) Crossing the plant with homozygous dominant purple flowered pea plant (PP) d. Crossing the plant with a plant whose genotype is unknown e. Crossing the plant with homozygous recessive white flowered pea plant (pp)
In the video game Animal Crossing: New Horizons, flowering breeding is based in genetics. Each flower's color is determined by the genotype at three or four unlinked genes: R, Y, W, and S. The genotype of the elusive blue rose is RR YY ww ss. In the game, one way to get a blue rose is to cross two roses with the Rr Yy Ww ss genotype. A) What types of gametes and in what proportions will a Rr Yy Ww ss rose produce? B) In a cross Rr Yy Ww ss x Rr Yy Ww ss what are the possible offspring genotypes and at what frequency will they each appear? Show your work. C) What proportion of the offspring of the cross will be blue roses?
In corn plants, two pairs of genes control color in the ears of corn. The following genotypes result in various colors: W-C- [red]; wwC- [yellow]; W-cc [white]; wwcc [white]. What is the phenotypic ratio of the dihybrid cross between corn plants heterozygous for both genes? (Dashes mean the allele could be W or w, i.e., WWCC/WwCC/WWCc/WwCc geneotype gives red color)
Imagine you are crossing two plants that have these two genotypes—Tt and tt. What are the two genotypes of the gametes that the Tt plant can make? What is the one genotype of the gametes that the tt plant can make? Set up a Punnett square to analyze the cross. Does the Punnett square need to have four boxes or just two? If you were crossing a TT plant with a tt plant, how many boxes would be necessary in a Punnett square?
In corn, two independent, recessive nuclear genes, japonica (j) and iojap (ij), produce variegation (green and white striped leaves). Matings between individuals heterozygous for japonica always produce 3 green:1 striped individuals regardless of how the cross is performed. You have a variegated plant that could be either jj or ijij . What cross can you make to determine the genotype of this plant, and what results do you expect in the F1 generation in each case?
In Mendelfruit plants, fruit may be either round (RR), long (rr) or oval (Rr). Cross two oval-fruit plants. What is the phenotypic ratio of the resulting offspring? (what do they LOOK LIKE?) Cross a round-fruit plant and an oval-fruit plant. Give the phenotypic ratio of the offspring.
In corn plants, two pairs of genes control color in the ears of corn. The following genotypes result in various colors: W-C- [red]; wwC- [yellow]; W-cc [white]; wwcc [white]. What is the phenotypic ratio of the dihybrid cross between corn plants heterozygous for both genes? (Dashes mean the allele could be W or w)
In a test cross, an individual dominant for a certain trait ( whether homozygous or heterozygous is unknown) is crossed with a homozygous recessive individual. A plant with spherical seeds is crossed with another plant. If the genotypes and phenotypes of the offspring are 100% heterozygous and 100% dominant, what were the genotypes of the parents? (hint: try multiple crosses until you find what works) If the genotypes and phenotypes of the offspring are 50% heterozygous spherical seeds and 50% wrinkled seeds, what were the genotypes of the parents?
In corn plants, a dominant allele (K) allows kernel colour and a recessive allele (k) inhibits kernel colour when homozygous. On a different chromosome, the dominant gene P causes purple kernel colour and the homozygous recessive genotype causes red kernel colour.A true breeding white corn plant was crossed with a purple corn plant, yielding 50% red corn plants and 50% purple corn plants.What are the genotypes of the parental corn plants? Select one: a. KKPp kkpp b. KkPP kkPP c. kkPp KkPp d. KKPP kkPp
In the tomato plant, red fruit (R) is dominant over green (r). Smooth fruit skin (S) is dominant over peachy skin (s). The genes for fruit colour and fruit texture are linked on the same chromosome. A heterozygous red, heterozygous smooth plant was crossed with a green, peachy plant. The results are given:Smooth-red = 28Smooth-green 567Peachy-red = 534Peachy-green = 34i. Calculate the map distance between the genes.ii. The map distance calculated in (i) is not representing the true distance between the genes? Provide your argument.
