Question

A cross that between mice that differ by only two traits (e.g. eye color and coat color) is called a ______.

Answer 1

The question lacks options, the options are:

A) hybridization

B) gene cloning

C) monohybrid cross

D) dihybrid cross

Step-by-step explanation:

Mendel, in one of his several experiments, performed a cross involving two different genes coding for two distinct traits in the organism. After crossing purebreeding organisms for different traits, he got an F1 generation that had a combination of both alleles of both genes in their genotype. These F1 offsprings were called DIHYBRIDS i.e they contained two different alleles for two different genes.

Mendel further crossed the dihybrids and called the cross, DIHYBRID CROSS. In this question, the mice contain different alleles for two different genes (eye color and coat color). Hence, the mice are called DIHYBRIDS and a cross between them is called DIHYBRID CROSS.
