Explanation:
Some of the mice will be homozygous dominant (AA), others will be heterozygous (Aa) and others homozygous recessive (aa).
Because the population isn't homogeneous, the easiest way would be to mate all grey mice on one side, and all yellow mice on the other, and analyze the phenotype of the offspring.
The cross between mice with the recessive trait will have <u>100%</u> offpsring with the recessive trait.
However, the cross between mice with the dominant trait will show some recessive individuals in the offspring:
- AA x AA ---> all A_
- AA x Aa ---> all A_
- Aa x Aa ---> 3/4 A_, 1/4 aa
