In guinea pigs, the allele for black fur (B) is dominant over the allele for brown (b) fur. A black guinea pig is crossed with a brown guinea pig, producing five F1 black guinea pigs and six F1 brown guinea pigs.

(a) How many copies of the black allele (B) will be present in each cell from an F1 black guinea pig at the following stages: G1, G2, metaphase of mitosis, metaphase I of meiosis, metaphase II of meiosis, and after the second cytokinesis following meiosis? Assume that no crossing over takes place.

(b) How may copies of the brown allele (b) will be present in each cell from an F1 brown guinea pig at the same stages? Assume that no crossing over takes place.
