There is also phenotype ratio.

dihybrid cross refers to the cross breeding of two different traits.

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 other plant displays the homozygous recessive traits of green seed color and wrinkled seed shape (yyrr).

When a true-breeding plant with yellow seed color and round seed shape (YYRR) is cross-pollinated with a true-breeding plant with green seed color and wrinkled seed shape (yyrr), the resulting offspring (F1 generation) are all heterozygous for yellow seed color and round seed shape (YyRr).

the ratio is 9:3:3:1.


Anushka2001: plzz mark it as the brainliest answer!!
tiaannbabu03: The ratio actually goes like this......
tiaannbabu03: Genotypic ratio:- 1:2:1:2:4:2:1:2:1. And...... Phenotypic ratio:- 9:3:3:1
tiaannbabu03: Phenotypic means the outer appearance of the plant where as genotypic means the difference of genes inside the plant..... Thank you
