Explanation:

Heterozygous individuals carry different alleles for the same gene locus.

Incomplete dominance occurs when both alleles are expressed in heterozygous organisms.

The Answer:In both the sexes of frog, each gonad remains attached to the kidney of same side. In human special ligaments attach the gonads to body wall. In males, testes is not abdominal in location; these are present in scrotal sac.

Appearance*In most frog species, the female is larger than the male, so frog size relative to a standard can be a good method of gender identification. In some species, the female frog is darker in color than the male, and in others, the male is darker.

Typically, frogs lay eggs. This process usually occurs through external fertilization, where the female releases her eggs from her body into water. Then, the male releases his sperm to fertilize them.In this case, the eggs are fertilized inside the female's body before they are released.
