what is heterozygus plants?
 Organisms have two alleles for each trait. When the alleles of a pair are heterozygous, one is dominant and the other is recessive.
Example:  The gene for seed shape in pea plants exists in two forms, one form or allele for round seed shape (R) and the other for wrinkled seed shape (r). A heterozygous plant would contain the following alleles for seed shape: (Rr).
