The color of the fur is the X genotype✔ phenotype.
The genetic combination of alleles that determine the fur color is called the ✔ genotypeX phenotype.
Suppose that a mouse with black fur has both an allele for black fur and an allele for white fur (Bb). Based on this information, you can conclude that the dominant allele must be for ✔ blackX white fur and
the recessive allele must be for black✔ white fur.
For this lab, assume that the allele for black fur is dominant. This allele’s symbol is ✔ BX b.
white fur✔ black fur
Generalize: If either allele is the ✔ dominantrecessive
allele for a trait, the organism will exhibit that trait. An organism will express the recessive trait only when no alleles areone allele is✔ both alleles are recessive
✔ BBbbX Bb.

The original mice that you cross are called the F1 generation✔ P generationF2 generation.
X white fur✔ black fur.
The offspring from that cross are called the ✔ F1 generationX P generationF2 generation.
