Answer:
the genotype of the mice in this lab is BBee, which results in a phenotype of black fur and black eyes.................
Step-by-step explanation:
Based on the information provided, the genotype of the mice in this lab is BBee, which means that they have the alleles B and E for fur color and eye color, respectively. The phenotype of the mice, which refers to their observable physical characteristics, is black fur and black eyes.
The B and E alleles are dominant, which means that they will mask the expression of the recessive alleles (b and e). Therefore, even if the mice have one copy of the recessive alleles, their fur will be black and their eyes will be black, because the dominant alleles are expressed.
To summarize, the genotype of the mice in this lab is BBee, which results in a phenotype of black fur and black eyes.
