What does Ploidy mean?

Number of Genomes in a cell, Haploid is 1 Copy, Diploid is 2 copies

3
New cards

Whats a Genome

DNA found in an organism

New cards

What happens in Meiosis 1

PMAT, Prophase 1, Chromosomes do recombination, Anaphase 1, Homologus Chromatids align at center, Metaphase, Spindles pull chromatids on each side, Telophase 1, chromatids at end of cell, nucleus forms around them

5
New cards

What happens in Meiosis 2

Same thing as Mitosis, this time 4 haploid cells are made

6
New cards

Trisomy

3 copies of one of chromsome

7
New cards

Non-disjunction

homologus chromatids don’t seperate during anaphase 1 of meiosis

make cells for growth, repair, and asexual reproduction and 2 daughter cells
