Early use of the test cross was as an experimental mating test used to determine what alleles are present in the genotype. An organism's genetic makeup is called its genotype, and it reflects all ...

In this genetic cross, the female alleles are Dd and the male alleles are dd. This cross is known as a backcross. Half of the possible offspring have the allele combination Dd, and the other half ...

This means that all the offspring produced will be tall. In this genetic cross, Parent 1 is still tall but is heterozygous with alleles Tt. Parent 2 is short and is homozygous with alleles tt.
