E) A gamete from this species has 4 chromosomes.
11. The karyotype of one species of primate has 48 chromosomes. In a particular female, cell division goes
awry and she produces one of her eggs with an extra chromosome (25). The most probable source of this error
would be a mistake in which of the following?
