Question

A reciprocal cross would be: 

विकल्प

• between a homozygous recessive individual and a homozygous dominant one with respect to one pair of traits

• between a homozygous recessive individual and a homozygous dominant one with respect to two pairs of traits

• between a homozygous recessive male and a homozygous dominant female, and a separate cross between a homozygous dominant male and a homozygous recessive female

• self-fertilization of an F₁ plant

Answer 1

between a homozygous recessive male and a homozygous dominant female, and a separate cross between a homozygous dominant male and a homozygous recessive female

Explanation:

A reciprocal cross involves two separate crosses where the sexes of the parents are reversed. For example, one cross uses a homozygous recessive male and a homozygous dominant female, and the reciprocal cross uses a homozygous dominant male and a homozygous recessive female. This type of cross helps in determining if a trait is sex-linked or autosomal by comparing the offspring of the reciprocal crosses. It differs from a single cross involving particular genotypes and is not just self-fertilization of an F₁ plant.
