Question

The tralt for purple flowers in pea plants is dominant to the trait for white flowers (pl. FIGURE 18: Heterozygous Homozygous Recessive Cross P pp pPp pp 6. What is the probability that the heterozygous parent will donate a recessive p allele? 7. What is the probability that the homozygous-recessive parent will donate a recessive paliele? 8. What is the probability of both parents donating a recessive p allele? 9. Why is the known genotype in a testcross always homozygous recessive? Provide an example to support your claim 10. For each pair, calculate the probability of producing a homozygous recessive genotype. Then place the pairs in order of increasing probability. a. Aa x da b. da x da C. Aa x A 11. Parents of genotype AABB and cabb were crossed and produced all heterozygotes with the genotype AaBb. Heterozygotes from the F, generation were crossed and produced a phenotypic ratio of 9:3:3:1.

Answer 1

hope it's clear..thanks
