During meiotic division, the

  • homologous chromosomes are seperated

  • linkage is disturbed

  • homologous chromosomes do not segregate

  • All of the above

Solution

A.

homologous chromosomes are seperated

Meiotic division occurs in reproductive system or germ cells. After meiosis, four haploid cells are present which are not identical to their parents. Homologous chromosomes form bivalent by pairing and each of them is seperated. They move towards the opposite poles of the spindle fibres. Each daughter cell receives a haploid set of chromosomes.
