Question

The offspring of a monohybrid test cross would show the genotype:

विकल्प

• AA and Aa

• Aa and aa

• AA, Aa, and aa

• AA only

Answer 1

Aa and aa

Explanation:

In a monohybrid test cross, an individual with an unknown dominant genotype (Aa) is crossed with a homozygous recessive individual (aa). The offspring will inherit either the dominant allele (A) or the recessive allele (a) from the heterozygous parent and only the recessive allele (a) from the homozygous recessive parent. As a result, the offspring genotypes will be either Aa (heterozygous) or aa (homozygous recessive) in a 1:1 ratio.
