A genetcist crossed pure breeding black mice (88) with pure breeding brown
mice (bb). AI the mice in the F, generation had black ceats. When these mice
were crossed, they yieided 951 black-coated mice and 317 brown-coated mice.
The Punnett square describes this cross. The numbers 1 1o 4 are shown instead
of the genotypes for the offspring

Expert Solution
Step 1

Dominant trait is the trait in which the phenotypic expression is dependent on even a single allele that is dominant. 

Recessive trait requires the homozygous condition in order to be expressed in the generation.

When a pure line is treated with another pure line, it is observed that all the offsprings in the F1 generation tends to be phenotypically that of the dominant character while the recessive traits are expressed in the F2 generation.
