Skyla Peck · Answer 1

The correct answer is A.

In human male gonads, diploid cells with 46 chromosomes consisted of 2 chromatids undergo a process of meiosis to form 4 haploid sperm cells.

In the process of meiosis, the two sets of chromosomes are firstly divided into two cells with a haploid number of chromosomes, 23.

These two cells undergo a second set of divisions in which each chromosome is divided into two chromatids, resulting in 4 cells with 23 chromosomes
