Question

Second-generation offspring from a cross are the ______.

Options

• F₁ generation

• F₂ generation

• hybrid generation

• none of these

Answer 1

Second-generation offspring from a cross are the F₂ generation.

Explanation:

In Mendelian genetics, the parental generation is labeled P, the first offspring generation as F₁, and the second offspring generation resulting from F₁ crosses as F₂. Traits that were masked in the F₁ generation by dominant alleles can reappear in the F₂ generation in a typical 3:1 ratio for a monohybrid cross, which demonstrates the principle of segregation of alleles during gamete formation.
