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
