In summer squash, fruit color and shape are inherited as single gene, autosomal traits. White fruit color (W) is dominant over yellow fruit color (w) and disk-shaped fruit (D) is dominant over sphere-shaped fruit (d).a. Suppose two squash plants with the following genotypes are mated: WwDd x WwDd. What proportion of the offspring from this cross is expected to have?O white, disk-shaped fruitO white, sphere-shaped fruitO yellow, disk-shaped fruitO yellow, sphere-shaped fruitb. Suppose two squash plants with the following genotypes are mated: Wwdd x wwDd. What proportion of the offspring from this cross is expected to have?O white, disk-shaped fruitO white, sphere-shaped fruit
