Chapter 3 and Meiosis Flashcards
gametes
sex cells ( sperm and egg)
Homologous pair
one from mom and one from dad
Prophase 1
crossing over of homologous pairs
Metaphase 1
homologous chrs, line up (spindle checkpoint)
Anaphase 1
homologous chrs. seperate
Cells after telaphase and cytokinese 1 in
meiosis are
HAPLOID
Anaphase 2
sister chromatids seperate
what do you end up with at the end of Meiosis?
4 genetically different haploid cells
continual meiosis happening
spermatogenesis
sporadic meiosis of gametes
oogenesis
meiosis creates 4 genetically different sperm
spermatogenesis
meiosis creates 1 egg plus 3 polar bodies
oogenesis
meiosis 2 finishes to produce sperm
spermatogenesis
meiosis 2 doesnt finish until fertilization
