how can meiosis occur in animals having odd number of chromosomes like mules (63 chromosomes) ? how will be the no.of chromosomes divided among the daughter cells?

Dear student,
Please find below the solution to the asked query

The normal meiosis needs even number of chromosomes to distribute chromosomes evenly in daughter cells. The organisms like mule that posses an odd number of chromosomes (63 chromosomes) cannot undergo normal meiosis and produce viable gametes. The single chromosome cannot be divided into half during meiosis, it cannot produce daughter cells with 31.5 chromosomes. Hence, no meiosis or normal meiosis occur in animals with odd chromosomes and hence they are sterile.

Hope this information will clear your doubts about the organisms with odd number of chromosomes.
