Question

a)1 The allele for tall pea plants is dominant over the allele for short pea plants. If two heterozygous plants are crossed, what will the genotypic and phenotypic ratios be?

b)2 Purple flowers are dominant over white flowers, and green pods are dominant over yellow pods in pea plants. What would the probability be of producing a pea plant with white flowers and yellow pods from parent plants that are heterozygous for each trait?

c)3 Red eyes are dominant on fruit flies but an x-linked recessive allele will produce white-eyed flies. If a pure breeding red-eyed female mates with a white-eyed male, what is the probability of white eyes in the F1 generation?
