The two different phenotypes in the dihybrid cross are seed color and seed shape. One plant is homozygous for the dominant traits of yellow seed color (YY) and round seed shape (RR). The genotype can be expressed as (YYRR). ... The F2 progeny exhibits four different phenotypes and nine different genotypes

Di-hybrid Cross in genetics
Explanation:
- A dihybrid cross is a rearing test between P age (parental age) life forms that contrast in two qualities. The people right now cross are homozygous for a particular characteristic or they share one quality. Qualities are attributes that are controlled by portions of DNA called genes.
- In a dihybrid cross, parent life forms have various sets of alleles for every characteristic being contemplated. One parent has homozygous prevailing alleles and the different has homozygous latent alleles.
- Self-fertilization of these F1 generation plants brings about posterity, a F2 generation, that display a 9:3:3:1 phenotypic proportion in varieties of seed shading and seed shape. See this spoke to in the graph. This proportion can be anticipated utilizing a Punnett square to uncover potential results of a hereditary cross.
- Genes that control multiple unrelated features are said to be pleiotropic. For example, Mendel’s flower color gene specifies a protein that causes colored particles or pigments.
