1. In one experiment, Mendel crossed a pea plant that bred true for axial flowers with a pea plant that bred true for terminal flowers. All the F1 plants had axial flowers. Which is the recessive trait? Explain your answer. 2. Green pod color is a dominant allele in pea plants (G). If two plants with green pods are crossed, some of the offspring have yellow pods. What are the possible genotypes of the parents? 3. In garden peas, one...

2. A female Drosophila of unknown genotype was crossed with a white-eyed male fly, of genotype (w = white eye allele is x-linked recessive, W+= red-eye allele is dominant.) Half of the male and half of the female offspring were red-eyed, and half of the male and half of the female offspring were white-eyed. What was the genotype of the female fly?

d. What percent of the offspring will be carriers of the white yel! 2. Using the same information as for question #1, cross a heterozygous red-eyed female with a red-eyed male. 1. What are the genotypes of each parent? b. What fraction of the children will have red eyes? c. What fraction of the children will have white eyes? d. What fraction of the female children will carry the white eyed trait? 3. In humans, hemophilia is a sex-linked recessive...

Assume red plumage is encoded by an autosomal dominant allele (R). You crossed a male robin with a red breast and a homozygous dominant genotype with a female robin with a homozygous recessive genotype. You get both male and female offspring, but find that only the male offspring have a red breast. How could you explain this? Group of answer choices a The red plumage has variable expressivity in males b The plumage gene is not present in females c...
