Meiosis:
Diploid cell: 2n half chromosomes come from 1 parent and half from another parent.
Homologous: each of male chromosomes has a corresponding chromosome from a
female.
Haploid: single cell. Represented as n. Sex cells (gametes) are haploid.

-cytokinesis follows telophase 1, forming
2 new cells.
CHROMOSOMES BECOME VISABLE-DO
NOT MAKE TETRADS
CHROMOSOMES LINE UP IN MIDDLE
THE PAIRED CHROMATIDS SEPARATE
FOUR DAUGHTER CELLS PRODUCED
Gametes: egg and sperm formed by meiosis => fertilized becomes a zygote then
the zygote undergoes mitosis.
Mitosis: when 2 sets of genetic material separate each daughter cell receives one
complete set of chromosomes.
Meiosis: homologous chromosomes line up and move to separate daughter cells. As
a result segregation takes place. Meiosis changes chromosome number by half.
