A cross is made between a pea plant with round, yellow seeds (WwGg) and one with wrinkled, green seeds (wwgg). The progeny that resulted had the following traits: round, green: 82 round, yellow: 18 wrinkled, green: 10 wrinkled, yellow: 90 1. Which alleles were on which chromosome in the doubly heterozygous parent? 2. What is the distance in cM between these two genes?

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.

In pea plants, round peas (R) are dominant to wrinkled peas (r). You do a test cross between a pea plant with wrinkled peas (genotype rr) and a plant of unknown genotype that has round peas. You end up with three plants, all which have round peas. a) From this data, can you tell if the round pea parent plant is homozygous dominant or heterozygous? Explain. b) If the round pea parent plant is heterozygous, what is the probability that...
