Genetic Variance in Meiosis

Does random orientation occur in both metaphase 1 and metaphase 2?

No.

In metaphase I homologous CHROMOSOMES can orientate so either one is pulled to either side. One chromosome is maternal and one is paternal so it will make a difference which side each one goes to as the two homologous chromosomes are genetically different.

In anaphase II it is the chromosome itself which is split apart. In metaphase II only one of each type of chromosome is present so no random orientation will occur.

Hope that helps!
