daughter
cells, creating
4 haploid
cells
Variation in Meiosis:
Independent
Segregation
- homologous pairs line up,
random
which side each pair seperated into,
large
number of combinations
Crossing
Over
- chromatids
twist
,
tension
causes chromatid to break,
recombine
with another chromatid creating a new
allele
combination
