Question 1

What happens during interphase

Answer 1

Chromosomes double and are attached with a centromere

Question 2

What happens during prophase 1 (meosis)

Answer 2

Nuclear envelopes break down
Bivalemt chromosomes pair up
Crossing over occurs

Question 3

What happens during metaphase 1 (meosis)

Answer 3

Bivalents line up at the equator
Independent assortment

Question 4

What happens during anaphase 1 (meosis)

Answer 4

Homologation pairs are pulled to separate sides
Chromosomes break and rejoin- chiasmata

Question 5

What happens during telephone 1 (meosis)

Answer 5

Cytokinesis occurs creating a haploid cell

Spindle fibres break down

Question 6

What happens during prophase 2 (meosis)

Answer 6

Nuclear envelope breaks down
DNA coils and condenses
Spindle fibres reform

Question 7
