Meiosis I

Somatic vs Sex Cells

somatic cells are diploids and have two sets of each chromosome while sex cells are only sperm and egg cells

What are homologous chromosomes

two of the same chromosomes coming together to share DNA, one is from mom and the other, from dad

outcomes of meiosis

genetic reduction, genetic recombination

Interphase

same as mitosis in somatic cells

Prophase I

same as in mitosis, except the chromosomes group into TETRADS and synapsis occurs

Metaphase I

tetrads line up in the middle of the cell and the spindle fibres begin to form, independent assortment occurs

Anaphase I

singular chromosomes are pulled apart by the spindle fibres and are now normal chromosomes (not tetrads), the centromeres are still present

Telophase I

two non-identical nuclei are present, and now the cell is a haploid
