Answer:
No, because the mule can not reproduce.
Step-by-step explanation:
Although the fusion of a donkey's and a horse's gametes can produce a viable offspring called mule, the mule cannot reproduce i.e. it is sterile, because the two parents are different species. Organisms of different species contains different number of chromosomes in their cell. The horse contains 64 chromosomes and a donkey contains 62 chromosomes. Both organisms undergo meiotic division to produce gametes with 32 and 31 chromosomes respectively.
These gametes fuse during fertilization to form the MULE offspring with a total number of 63 chromosomes in each cell (32+31). Before a sexually-reproducing organism can produce gametes via meiosis for reproduction purposes, it must contain a complete set of chromosomes. A mule contains an incomplete set of chromosome (63) i.e. has extra chromosomes than diploid (2n + 1). Due to this reason, a mule cannot undergo meiosis, and hence cannot produce gametes making it a sterile organism.
This sterile nature of the mule arises because of the different species of animals (horse and donkey) that produced it.
