Question

Can someone tell me about mules that sometime reproduce?

Answer 1

I have never heard of this, but I suppose it could be possible

Answer 2

these hybrids don't typically reproduce because of uneven chromosome division in meiosis so when those s*x cells meet other s*x cells the chromosomes don't pair up properly. but sometimes divisions in meiosis may produce cells with the right number of chromosomes for proper pairing. but this is a really simple way of putting things.

another example of hybrid "fertility" is the random, lone, black seed in a seedless (hybrid) watermelon.

Answer 3

Can Mules Reproduce? Or FERTILE MULES?   (Mules giving Birth/Mule gives Birth/Mule has a foal)    Do they have normal anatomy?

What is the offspring of a horse and a mule called? Can a mule have a baby?

Short answer - No, mules (both male and female) are sterile.  Both have normal anatomy internally and externally.  The males must be castrated, as they have the equipment but do not produce the essential element needed (we're trying to keep this PG here...)  Females may come into heat and may need hormone shots if heat is a problem.  

            For those who are following up with "Okay, what about the fertile mule we have read about..."  - Fertile mules (hinnies) are a 1 in 1 million case occurance. All known fertile hybrids in the equine world have been female mules or hinnies.  Why these few is still scientifically a mystery, and there is still scientific debate over the verification of some "Fertile"; cases.  The most well known and documented cases are of Krause, a mare mule with two mule sons, and a fertile hinny in China, who;s offspring, Dragon Foal, is considered unique.  The complications for Krause's cases is that her sire, Chester, is also the sire of her sons.  However, DNA testing has been cataloged as conclusive that both foals, Blue Moon and White Lighting, are Krause's foals.

           In most known cases of mule fertility, it has been noted that the mare mule passed on a complete set of her Maternal genes to the foal.  Therefore a female mule bred to a horse would produce a 100% horse foal.  Thus was the case of Old Beck, who was at Texas A&M in the 1920's;.  This mare mule had a mule daughter, Kit.  She was brought to TX A&M for observation.  She was bred to a saddle horse stallion, and produced a horse son, Pat Murphy Jr.  Pat Jr was fertile, and sired horse foals.  Beck aborted a third foal, sired by a jack, which although deformed, appeared to be a regular mule.

                There has more recently been a case of a mare mule in Brazil who has foaled two 100% horse sons.  Tests in the future will hopefully prove them to be normal, fertile stallions.

Answer 5

Yes, you see there are very few absolutes in Nature.  Even when Man interferes.  They are called hinnies.  They occur about one in a million times a mule is conceived.

It's actually quite interesting.
