polar bodies

Question 35

Independent assortment happens in which stage of miosis

Answer 35

Metaphase 1

Question 36

How does meiosis create genetic variation?

Answer 36

1: crossing over- matches with their homologensis pair and swaps genes at random
2 Independent assortment- random alignment in metaphase one
3: Segregation- random separation on genes

Question 37

3 major differences between
Meiosis 1 and 2

Answer 37

Meiosis one produces 2 diploid daughter cells
meiosis 2 makes 4 haploid cells
independent assortment and segregation happen during meiosis one
