Metaphase II chromosomes line up at metaphase plate, this time with one sister chromatid on either side. Anaphase II sister chromatids separate, 4. Telophase II and cytokinesis create two new cells, for a total of four haploid cells. B. Diversity is created 1. Recombination C. Role of meiosis and sex outcome 1.
Sex is determined by the sperm.
The revealing Y chromosome. It can be used as a hereditary marker, as in the case of Thomas Jefferson s descendants through Sally Hemings. Spermatogonia diploid cells that can divide by mitosis to make more of themselves, or make cells destined to become sperm called primary spermatocytes. Secondary spermatocytes complete meiosis II to make four total haploid spermatids. Spermatids are matured in about three weeks to form sperm with flagella tails, concentrated mitochondria, and a haploid nucleus.
