What is Monohybrid and Dihybrid phenotypic ratio?

In dihybrid crosses, inheritance of two traits is predicted. Parents of the dihybrid cross differ in two traits. If the alleles or the genes are not linked, the resulting phenotypic ratio of a monohybrid cross is 3:1 while in a dihybrid cross, it is 9:3:3:1.

What is the phenotypic ratio of a Monohybrid and dihybrid cross?

A monohybrid cross is defined as the cross happening in the F1 generation offspring of parents differing in one trait only.

What is Monohybrid Dihybrid ratio?

Monohybrid cross is a cross between two individuals that differ in only one observed trait. Dihybrid cross is a cross between two individuals that differ in two observed traits.

What is the cross called and what is phenotypic ratio?

A cross is made between two homozygous parent plants, is called monohybrid cross. In this cross F2 phenotypic ratio is 3:1 and genotypic ratio is 1:2:1. So, the correct option is ‘3:1’. Answer verified by Toppr.

What is difference between homozygous and heterozygous?

Homozygous: You inherit the same version of the gene from each parent, so you have two matching genes. Heterozygous: You inherit a different version of a gene from each parent. They do not match.
