Which represents a cross between 2 individuals heterozygous for a single trait?

Question

Quizplus · Accepted Answer

When two individuals heterozygous for a single trait are crossed, their genotypes are Aa. Therefore, the offspring will receive one allele from each parent and can inherit either an A or a. The Punnett square for this cross is:

| A  | a
--|---|---
A | AA | Aa
a | Aa | aa

From this, we can see that the expected genotype ratio for the offspring is 1 AA : 2 Aa : 1 aa. Therefore, the correct answer is choice E, Aa F1F1F1S1F1F1F10 Aa. This represents a cross between two individuals heterozygous for a single trait, producing offspring in the expected genotype ratio.
