Question 19 (1 point)

In squash, white (W) is dominant over yellow (w) and disk-shaped (D) is dominant over sphere-shaped (d). For the mating WwDd X WwDD, which best describes the expected offspring?

Question 19 options:

All will be the same genotype and phenotype.

2 different genotypes, all will be the same phenotype

4 different genotypes, 4 different phenotypes

6 different genotypes, 2 different phenotypes

8 different genotypes, 4 different phenotypes

	All will be the same genotype and phenotype.
	2 different genotypes, all will be the same phenotype
	4 different genotypes, 4 different phenotypes
	6 different genotypes, 2 different phenotypes
	8 different genotypes, 4 different phenotypes

Solution

the answer is 6 different genotype and 2 different phenotype and the explaination is shown by the cross below:
