A mule is a hybrid of parents from two different species, horses and donkeys. These species have different numbers of chromosomes: horses have 32 pairs and donkeys have 31 pairs. How many chromosomes does a mule have? (HINT: Indicate if you are talking about chromosomes OR pairs of chromosomes.)

Solution

A Mule has in total of 63 chromosome number. It inherits 32 chromosomes from male horse and 31 chromosomes from female donkey. And thus total number of chromosomes become 63. There are 31 pairs of chromosomes with trisomy at place. These Mules cannot breed of their own. They are sterile.
