Document Summary
Highlights differences between sexes and the similarities in development. More similar things between two genetic sexes than differences. Only a handful (400-500) are supported by the ovarian cycle. Peak of progesterone and estrogen help the _____ Starts during the maturational process of an egg undergoing meiosis. M1 is the replication and division of the egg. Replication, duplication of dna, separated to form two new cells. For gametes, there is another phase of meiosis called meiosis 2. Daughter cells divide to form 4 different haploid cells. Rather then completing the cycle of m2, the state of the egg is frozen just before ovulation (rather then forming 4 haploid, we have 2 diploid that haven"t divided) If supported by fsh, eggs will continue to grow until released into the fallopian tube. We have to have 2 gametes to meet. Complex process that has many synchronized events. By the time the sperms leave the testis, they are haploid.
