- 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

Explanation:
Due to technical problems, you will find the complete explanation in the attached files
Diploid cells = 2n = 46
Haploid cells = n = 23
therefore, there are 23 chromosomes in haploid cells.
