Answer:
Aa x Aa = AA (1/4), Aa (1/2) & aa (1/4)
Bb x Bb = BB (1/4), Bb (1/2) & bb (1/4)
Dd x dd = Dd (1/2) & dd (1/2)
ee x EE = Ee (1)
a).
The probability of obtaining a plant that is heterozygous for all four genes = AaBbDdEe = ½ * ½ * ½ * 1 = 1/8
b). The probability of obtaining a plant with the dominant phenotype for all four genes = A_B_D_E_ = ¾ * ¾ * ½ * 1 = 9/32

For this question you'll need to type your answer in the space provided: In pea plants, long stems are dominant to short stems, and green pods are dominant to yellow pods. What are the genotypes and phenotypes of offspring from a cross where one plant is heterozygous for both traits and the other plant is short stemmed with yellow pods? What percentage of each phenotype would you predict for this cross?

1. A pea plant with round seeds is crossed with a pea plant that has wrinkled seeds. For the cross, indicate each of the following: a) the genotype of each of the parents if the dominant phenotype is heterozygous. b) What gametes will each parent produce c) if two round plants from the Fl generation are crossed, what would be the resulting genotypes and phenotypes of the F2 generation? Provide the Punnett square as well as your answer below.

1. In humans, red-green color-blindness is a sex-linked (carried on the X chromosome) recessive trait. If a woman who is not color blind but whose father was color-blind marries a man who is not color-blind, what is the probability that their first child will be a daughter who is color- blind? a) 0 b) 25% c) 50%- d) 100%- e) cannot tell from the information given 2.

Part A - Deducing phenotypes and genotypes of selfed parents
Mendel studied pea plants dihybrid for seed shape (round versus
wrinkled) and seed color (yellow versus green). Recall that
the round allele (R) is dominant to the wrinkled allele
(r) and
the yellow allele (Y) is dominant to the green allele
(y).
The table below shows the F1 progeny that result from
selfing four different parent pea plants.
Use the phenotypes of the F1 progeny to deduce the
genotype and...

Assume that a cross is made between a heterozygous tall pea plant and a homozygous short pea plant.

Mendel crossed pea plants dominant for two different traits tall and green pods) with pea plants recessive for those same two traits (short and yellow pods).
