Explanation:
"The Y chromosome is a puny bit of DNA that has only a few genes. And the genes it does have mostly deal with being male. So the only traits that are passed from father to son through the Y are those that turn an embryo into a male and those that make a man fertile once he reaches puberty."
"Girls have two X chromosomes and boys have an X and a Y. Because girls have two X chromosomes, this means moms can only pass on an X to their kids. Boys have an X and a Y and can pass on either the X or the Y. So, it is actually your dad who determined if you were a boy or a girl!"
"This process is called meiosis. These gametes contain a unique copy of half the genes of the parent source. When fertilization occurs, an egg fuses and combines genetic material with a sperm to create a full set of chromosomal DNA, with 23 pairs of chromosomes"
