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.

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 ...

Biophysics, biochemistry, physiology, classical genetics and molecular genetics have all made their contributions, and myosin is now becoming one of the best-understood enzymes in biology.
