What type of genetic cross would involve two parents that are both heterozygous for a trait?

The scenario described involves two parents that are both heterozygous for a specific trait, which means they each have one dominant and one recessive allele for that trait (e.g., Aa x Aa). In genetics, a monohybrid cross is defined as a cross that examines the inheritance of a single trait and its alleles. When both parents are heterozygous, the resulting offspring can inherit a combination of these alleles, leading to a typical phenotypic ratio of 3:1 for the dominant trait to the recessive trait among the offspring.

For example, in a monohybrid cross between two heterozygous individuals (Aa x Aa), the possible genotypes of the offspring would be: AA, Aa, Aa, and aa. The resulting phenotypic ratio will show that 75% of the offspring are expected to display the dominant trait, while 25% would display the recessive trait.

In contrast, other types of crosses are focused on different genetic scenarios. A dihybrid cross involves studying two traits simultaneously, a test cross usually pairs an individual showing the dominant phenotype with a homozygous recessive individual to determine the genotype of the dominant individual, and a back cross refers to crossing a hybrid
