Metaphase I
During metaphase, motor proteins aid the microtubules in pushing and pulling the chromosomes.
The microtuble movements push and pull the chromosomes into position at the spindle equator.
All of the maternal or paternal chromosomes are not attached to one pole.
Since the initial connections between chromosomes and kinetochore microtubules are random, the alignment of the chromosomes at the spindle equator is random.
This random alignment allows for many combinations of paternal and maternal traits in the daughter cells, which leads to genetic diversity.
