The nerve may reach 2 meters long in some cases and may have branches.
Answer:
Black
Explanation:
In the mouse a certain colorless pigment precursor exists.
- If the B allele is present: precursor is converted into black pigment.
- If the genotype is bb: albino
In addition:
- If the A allele is present: black pigment is converted to brown pigment
- If the genotype is aa: black pigment is not converted and mouse remains black
If the mouse has a genotype aaBB, the colorless pigment is converted to black (because there is at least one B allele) but the black pigment cannot be converted into brown (because there's no A allele), so the mouse will have black fur,
