Question

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 of 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

Answer 1

Answer:

• G1: One copy of the B allele per cell
• G2: Two copies of the B allele per cell
• metaphase of mitosis: Two copies of the B allele per cell
• metaphase I of meiosis: Two copies of the B allele per cell
• metaphase II of meiosis: One copy of the B allele per cell
• second cytokinesis following meiosis: One copy of the B allele in only two of the four daughter cells.
