Why does crossing over occur in meiosis but not in mitosis? Explain gene mutations. Why can mutations in bacteria be a bad thing? Are mutations the result of genetic damage? Why must mutation be random according to the modern synthesis?
Does independent assortment occur in metaphase 1? Is embryonic development caused by mitosis or meiosis? What happens to the gametes if nondisjunction occurs at anaphase 2? Which event makes meiosis a reductional division and why? During which phase of meiosis does crossing over of chromosomes occur...
Where does fertilization of an egg cell usually occur? Ovulation & Fallopian Tube: The mammalian female provides her half of her progeny's embryo's genetic material through what is called an egg (also called an ovum). On a cycle, the female will ovulate and her egg will travel the length...
