Detailed explanation-1: -The cross involving only one pair of contrasting characters is called the monohybrid cross. For example, crossing two pea plants and considering their height as the only trait in the cross. Q. A cross in which a single pair of contrasting characters is studied at a time is called a dihybrid cross.

Detailed explanation-2: -Cross involving only one pair of contrasting characters is called monohybrid cross.

Detailed explanation-3: -Dihybrid cross-refers to inheritance of two pairs of contrasting characters by two parents at the same time.

Detailed explanation-4: -“A monohybrid cross is the hybrid of two individuals with homozygous genotypes which result in the opposite phenotype for a certain genetic trait.” “The cross between two monohybrid traits (TT and tt) is called a Monohybrid Cross.” Monohybrid cross is responsible for the inheritance of one gene.

Detailed explanation-5: -A monohybrid cross is defined as the cross happening in the F1 generation offspring of parents differing in one trait only. A dihybrid cross is a cross happens F1 generation offspring of differing in two traits.
