Anaphase 2
Telophase 2 and cytokinesis
Interphase
DNA replicates
Prophase
DNA pairs up
Metaphase
DNA meets in the middle
Anaphase
Chromosomes are pulled apart
Telophase
2 nuclei are formed
Cytokinesis
Cytoplasm splits
Crossing over
The chromosomes line up side by side and their chromatids cross over at points called chiasma
Effect of crossing over
Pieces of chromatid have swapped places resulting in new combinations of alleles
Homologous chromosomes
2 chromosomes similar in shape and size and carry the same gene sequence
Chromosome structure
Chromatid
Centromere
Independent assortment
When homologous chromosomes pair the pair independently of every other pair which leads to many possible combinatiojs
Independent assortment equation
2^n
Where n is the number of chromosomes
