gametes - sex cells
meiosis - formation of gametes in males and females
testis and ovary - where meiosis occurs; produce gametes
During meiosis, one cell undergoes two consecutive cell divisions to produce four daughter cells, each having half as many chromosomes as the parent cell.
two divisions of meiosis
meiosis I
meiosis II
Before meiosis begins, all the chromosomes are duplicated.
early prophase I - at the beginning of meiosis, each of the 46 chromosomes consists of 2 chromatids connected by a centromere
middle prophase I
synapsis - chromosomes align as pairs
the pairing of the chromosomes brings 2 chromatids of each chromosome close together
