Day 26: National Mule Day

Did you know a mule could be many things?

It’s the offspring of a male donkey and a female horse and is usually infertile because donkeys and horses have different numbers of chromosomes — 62 for a donkey and 64 for a horse.

The mule has 63 chromosomes and sits in the middle, hence the usual infertility.

But there are exceptions like the mule that gave birth to a mule during Xerxes’ invasion of Greece in 480BC.

Or two offspring of a female mule called Old Bec in the late 1920s, in Texas.

Mules can also be:

  • an obstinate person
  • a courier for illegal drugs
  • a hybrid plant or animal, especially a sterile one
  • any of several standard cross-bred varieties of sheep

So, set a timer for 5 minutes and write about whatever comes into your head when you think of the word “mule.”

Happy writing!
