Question

if the color white (p) is recessive and purple (q) is dominant, what color would result if pp and qq were crossed? all white hybrids all white purebreds all purple purebreds all purple hybrids

Explanation:

Step1: Determine the gametes

The parent with genotype \(pp\) can only produce gametes with \(p\). The parent with genotype \(QQ\) can only produce gametes with \(Q\).

Step2: Analyze the offspring genotype

When \(p\) (from \(pp\)) combines with \(Q\) (from \(QQ\)), all offspring will have the genotype \(Qp\) (or \(pQ\), order of alleles doesn't matter in this context).

Step3: Determine the phenotype based on dominance

Since \(Q\) (purple) is dominant over \(p\) (white), the \(Qp\) genotype will express the dominant trait. And since all offspring have the \(Qp\) genotype, they are hybrids (heterozygous) and show the purple color.

Answer:

all purple hybrids
