Explain Mendel's Dihybrid ratio with the help of anyone cross
This is indicative of a dihybrid cross. A dihybrid cross is simply a cross between two different individuals heterozygous at two different genes. By applying Mendel's law of inheritance, we helped Adrian to explain the 9:3:3:1 ratio produced by his experiment.
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.
