Document Summary
Conception: father"s sperm + mother"s ovum = zygote with 46 chromosomes in total, after embedding of chromosomes, bio mom is giving nutrients to embryo doesn"t happen until. Mitosis: mitosis begins after fertilization, the process by which a cell separates chromosomes in its nucleus into two identical cells, the identical splitting of cells. Reading rocks reading disabilities have: people with glasses have a gene mutation, and dead straight hair is a mutation too, some are lethal, like spontaneous miscarriage; some result in exceptionalities. Meiosis & crossing-over: chromosomes within sperm cells divide in half before they fertilize an ovum or egg cell, but the genetic material that goes into it is random, and that randomness only goes into splitting of. 23rd pair of chromosomes: males have x and y, females have x and x, sex of child determined by father"s sperm, the 23rd chromosome is the sex chromosome only sex chromosome, doesn"t do anything else.
