The Greater The Differences In The Dna The Greater The Level Of.
In biology, symbiosis describes any interaction between two biological organisms that is mutualistic, commensalistic, or parasitic. Horses ( equus caballus) and donkeys ( e. A zebroid (also zedonk, zebra mule, and zebrule) is the offspring of any cross between a zebra and any other equine:
Coyotes And Wolves Have The Same Number Of Chromosomes.
The further apart two animals are in genetic terms, the less likely they are to produce viable offspring. In short this means its a hybrid or cross between two different animal species. Such encounters can affect the conservation and evolution of a species.

Horses have 64 chromosomes and donkeys 62, so when the two breed their mule offspring ends up with 63. In normal animals, because their father and mother are from the same species, the genetic information that are exchanged from their mother/father to their father/mother can still be processed. The different hybrids are generally named using the portmanteau convention of sire’s name + dam’s name.
The Dzo Or Yakow Is A Bovine Hybrid, And Comes About From Cross Breeding A Yak With A Domestic Cow.
All the females born from this cross are fertile, and they can be bred back with either of the original species. Horses and donkey's do not produce fertile offspring because of differences in the dna. ( wikimediacommons/henry scherren) dodo shows.
In Most Cases, The Sire Is A Zebra Stallion.
Hybrids are often, but not always, sterile (think of mules). The resulting animal is much larger than a cow or a yak, and is thought to be much more productive in milk and meat production. The tiny egyptian plover bird has the courage of a lion.
