2
Which form of reproduction is related to mitosis? Why? Which form of reproduction is related to meiosis? Why?
3
The rod like structures within a cell which contain the DNA. Humans have 46 chromosomes in each cell. ◦ Bats-44 ◦ Potatoes-48 ◦ Camels-70 ◦ Flies-8
5
A cell divides into two identical cells. Each daughter cell or offspring has the same number of chromosomes as the parent cell.
6
Occurs in single celled organisms and all normal cells in the body. Asexual Reproduction!
8
Cell division which makes gametes. One cell splits into four cells, each with half the number of chromosomes as the parent cell. ◦ Human sperm and egg cells have 23 chromosomes.
9
Daughter cells have different DNA than the one parent cell. Only sexually reproducing organisms go through meiosis.
11
Artificial asexual reproduction. A body cell is taken from an organism and the nucleus is removed. The nucleus is transplanted into an egg cell of the same organism. When the egg develops, it is a genetic clone of the original organism.
12
DNA cloning-only a small portion of an organisms DNA is copied and “pasted” into another organism. The new DNA begins to replicate. Reproductive cloning-making an exact copy of an organism. ◦ Sheep, pigs, cows, cats and rabbits. Embryo cloning-cloning the human embryo to harvest and study stem cells.
