Ok, so when a horse (with 64 chromosomes) is crossed with a donkey(that has 62 chromosomes), each parent give its child half of its chromosomes. [64/2=32] [62/2=31]. So the mule gets 31 pairs of chromosomes plus 32 pairs of chromosomes. That equals 63 total chromosomes. In order to be a parent, it must give <span>half of its chromosomes to its child. [63/2=31.5] You can't have half a chromosome, so the mule is a sterile organism. Let me know if you have questions.</span>

Answer:
Lactase
Explanation:
Lactaid is a medication that contains the milk protein digesting enzyme Lactase. It is an enzyme supplement for those people who have trouble in digesting milk and other dairy products. Such condition occurs in Crohn's disease and termed as lactose intolerance. Lactase specifically acts on the lactose containing substrates and digests them by enzymatic activity. So people with lactose intolerance can be able to take dairy products with the help of Lactaid.
