Homozygous and heterozygous cross
WebBecause heterozygotes could arise from two different pathways (receiving one dominant and one recessive allele from either parent), and because heterozygotes and homozygous dominant individuals are phenotypically identical, the law supports Mendel’s observed 3:1 phenotypic ratio. WebStep 1/3. To solve this, we just need to find out the possible point of across that will generate a+b+ gamete. Let us find out.
