Humans autosomal cells have two copies each of 23 unique chromosomes. Match each cell division event and cell type according to the number of chromatids present. a. primary oocyte arrested prior to ovulation
b. spermatozoa
c. oogonium prior to S phase
d. secondary polar body
1. 23 Chromatids
2. 44 Chromatids
3. 92 Chromatids

a. primary oocyte arrested prior to ovulation >> 44 Chromatids

b. spermatozoa >> 23 Chromatids

c. oogonium prior to S phase >> 92 Chromatids

d. secondary polar body >> 23 Chromatids

Explanation:

An immature ovum can be defined as a cell that after oogenesis produces an ovum. The development of an immature ovum involves the following stages: oogonium (46 chromosomes, 2 chromatids),  prymary oocyte (46 chromosomes, 4 chromatids), secondary oocyte (23 chromosomes, 2 chromatids), ootid (23 chromosomes, 1 chromatid) and mature ovum (23 chromosomes, 1 chromatid).

The secondary oocyte after the second meiotic division produces a mature ova and a secondary polar body (haploid, 23 chromosomes, 1 chromatid), which generally is not fertilized.

The spermatozoa are male haploid gametes (23 chromosomes, 1 chromatid) developed from germ cells.

b is the best answer for this question.
