Question

When F₁ individual is crossed with its either of the two parents, the cross is known as ______.

Options

• test cross

• back cross

• reciprocal cross

• monohybrid cross

Answer 1

back cross

Explanation:

When an F₁ individual is crossed with either of its two parents, this type of cross is known as a back cross. This is often done to study the inheritance of specific traits and to recover parental genotypes. If the F₁ individual is crossed specifically with the recessive parent, this back cross is called a test cross, which helps to determine the genotype of the F₁ individual (whether it is homozygous or heterozygous).
