Answer:
There are 32 number of chromosome in egg cells of female horse while 31 number of chromosome in sperm of male donkey so the offspring produce from this fusion is mule having 63 number of chromosome.
Explanation:
Sperm and egg cells are the type of sex cells that contain half number of chromosome. Total number of chromosomes in horse is 64 and its half is 32 while total number of chromosome in donkey is 62 and its half is 31. So the mule have 63 number of chromosome.
