Question

A cross between two squash plants that produce yellow squash results in 124 offspring: 93 produce yellow squash and 31 produce green squash. What are the likely genotypes of the plants that were crossed?

Answer 1

Answer:

Both Yy

Explanation:

1. As  given here,

Total offspring are= 124;

that produce yellow squash= 93;

that  produce green squash= 31;

2. Let Y  for yellow producing squash and y for green squash;

Y is dominant over y.

3. Cross between two yellow squash producing plants

Genotype of parents = Yy and Yy

offspring = YY, Yy, Yy and yy,

as Y is dominant over y, so YY and Yy all produce yellow squash, and yy  produce green squash.

4. Their phenotypic ratio is 3:1 , as in question 93: 31

Answer 2

Answer:

Both Yy
