Which of the following best describes egg production in the female reproductive system?
a diploid cell undergoes meiosis to produce one egg and 3 polar bodies with 23 chromosomes each.
a diploid cell undergoes meiosis to produce four egg cells with 23 chromosomes each.
a haploid cell undergoes meiosis to produce four egg cells with 23 chromosomes each.
a haploid cell undergoes meiosis to produce one egg and 3 polar bodies with 23 chromosomes each.

A diploid cell undergoes meiosis to produce one egg and 3 polar bodies with 23 chromosomes each.

Explanation:

During egg formation in the ovary, Primary oocyte (diploid) having 46 chromosomes undergoes meiosis I to form one secondary oocyte and one first polar body. Both the secondary oocyte and one polar body are haploid having 23 chromosomes.  Both daughter cells then undergo meiosis II, the first polar body divides to give two polar bodies and the secondary oocyte divides by meiosis II to form one ovum. Therefore, during egg formation in the reproductive system, a diploid cell (a primary oocyte) undergoes meiosis to produce one egg and 3 polar bodies with 23 chromosomes each.
