What type of cells are made from a secondary oocyte?

A secondary oocyte undergoes the second meiotic cell division to form a haploid ovum if it is fertilized by a sperm. Oogenesis begins with oogonia (singular, oogonium), which are the immature eggs that form in the ovaries before birth. Oogonia are diploid cells and are equivalent to spermatogonia in males.

Explanation:

amber has allowed scientists to study dna that has been preserved over millions of years.

the answer would be 2, if crossing over doesn’t occur 2 out of 4 of the daughter cells will have that allele.

hope this : )
