🤓 Based on our data, we think this question is relevant for Professor Melkonian's class at CSU.
From the given problem, note that the parents of the first cross was a dihybrid (let's say VvLl) and a homozygous recessive (vvll). The possible genotype ratio of the offspring for this cross is 1 VvLl : 1 Vvll : 1 vvLl : 1 vvll. This does not deviate far from the given offspring.
A violet-flowered, long-stemmed hybrid pea plant was crossed with a true-breeding white-flowered, short-stemmed pea plant with the following offspring: 47 violet, long-stemmed plants; 40 white, long-stemmed plants; 38 violet, short-stemmed plants; and 41 white, short-stemmed plants. If two of the white, long-stemmed plants above were crossed, you would expect to get which of the results listed below?
A. all white, long-stemmed
B. 1/2 white, short-stemmed; 1/2 white, long-stemmed
C. 3/4 white, long-stemmed; 1/4 white, short-stemmed
D. 9/16 violet, long-stemmed plants; 3/16, white, long-stemmed plants; 3/16 violet, short-stemmed plants; 1/16 white, short-stemmed plants
E. They do not all have the same genotype so the expected progeny can not be determined
