the only cells in your body that are haploid sex cells
another term for sex cells gametes
number of daughter cells produced at the end of meiosis 4
number of human chromosomes in each daughter cell 23
daughter cells are haploid or diploid? haploid
What does PMAT stand for? prophase, metaphase, anaphase, telophase
What happens at the beginning of Meiosis I? DNA IS copied so that there are now 92 chromosomes to be split
What happens at the beginning of Meiosis II? DNA is NOT copied so there are 46 chromosomes to be split
TETRADS refer to the chromosomes in which stage of Meiosis? Meiosis I
CHROMATIDS refer to the chromosomes in which stage of Meiosis? Meiosis II
What are the cells produced after telophase II? daughter cells
In which stage of Meiosis do the chromatids split by being pulled apart by spindle fibers? Anaphase II
In which stage of Meiosis do the tetrads split by being pulled apart by spindle fibers? Anaphase I
In which stage of Meiosis do the tetrads line up in the center of the cell? Metaphase I

In which stage of Meiosis does the cell's nuclear wall disintegrate and the DNA replicate? Prophase I
In which stage of Meiosis do the two cells' nuclear walls disintegrate and the DNA does NOT replicate? Prophase II
In which stage of Meiosis do the nuclear membranes reform at the end of cell division and 4 daughter cells are produced? Telophase II
In which stage of Meiosis do the nuclear membranes reform and 2 diploid cells are produced? Telophase I
What is the purpose of Meiosis? to produce haploid gametes
male gametes sperm
female gametes eggs
