Review Vocabulary: The process in which a cell's nucleus divides, producing two new daughter cells with their own set of chromosomes is called ____.
The body cells of animals and most plants, contain how many of each kind of chromosome?
The term that means a cell has a pair of each chromosome ( 2 of each kind) is ______.
Sex cells, (egg and sperm) are called gametes. According to your textbook, How many of each chromosome do gametes contain?
The term given to cells that contain only one of each chromosome is called what?
If an animal has 32 chromosomes in its body cells so that its diploid number is 32, what would be the haploid number of chromosomes in its sex cells?
If the gametes (sex cells) of an animal each have 16 chromosomes, then how many chromosomes will the fertilized egg have when the egg and sperm combine?
You can see that in order to maintain the correct number of chromosomes in each cell, gametes (sex cells) need to have half the number of chromosomes as body cells. In order to do this when gametes are formed, they go through a special kind of cell division that reduces the number of chromosomes by half. This type of of cell division is called _____.
During meiosis, one diploid cell will eventually form ____ (How many?) haploid gametes.

Zygotes develop into a multicellular organism by the process of _____.
The process of forming haploid gametes which then fuse together to form a diploid zygote which develops into a new adult organism is called _____ ______.
All your body cells have two of each chromosome. In other words, they come in pairs. That is because your cells get one chromosome in each pair from your _____ and the other one from your ____.
