You can easily tell the phenotypic ratio is 3:1 or 3/4 to 1/4. In the name "Dihybrid cross", the "di" indicates that there are two traits involved (e.g. R and Y), the "hybrid" means that each trait has two different alleles (e.g. It's also the perfect place to get some basic knowledge on the construction of genetic squares and learn some inheritance rules! Please ensure you entered the parent genotypes correctly, with both alleles of one gene coming before both of the other, and in the same order. Mother's genotype. AA. We can either count the combinations in the Punnett square, or use the dihybrid cross calculator to compute it for us. This means that both parents have recessive alleles, but exhibit the dominant phenotype. R and r, or Y and y), and "cross" means that there are two individuals (usually a mother and father) who are combining or "crossing" their genetic information.
