Question

In a mendelian monohybrid cross, which generation is always completely homozygous?

पर्याय

• F₁ generation

• F₂ generation

• F₃ generation

• P generation

Answer 1

P generation

Explanation:

In a Mendelian monohybrid cross, the P generation (parental generation) consists of individuals that are true-breeding, meaning they are homozygous for the trait in question. The F₁ generation produced from crossing two homozygous parents is always heterozygous, while the F₂ and further generations segregate into homozygous and heterozygous individuals. Thus, only the P generation is always completely homozygous.
