The heterozygous for three characteristics have 9 possible genotypes.
Explanation:
There are three types of genotypes. The homozygous dominant (AA), Homozygous recessive (aa) and heterozygous (Aa). Genotypes are the specific combination of alleles present in the individual. Genotypes are the genetic makeup of the cell and it is the genetic identity of an individual. Heterozygous means combination of particular alleles.
Genotypes are normally expressed in capital and small letters. When heterozygous three characteristics in genotype link with each other according to Mendel’s law produce offspring of nine different characteristics.
