When Mendel bred a plant with yellow peas with a plant with green peas, in the next generation all the plants had yellow peas.  This is due to the fact that...

Homozygous pairs result when the alleles are:

The heterozygous organism has:

The genotype is the set of alleles (ie. YY, Yy, or yy).  The phenotype is...
