Hi Paul, Quote: |
It's feasible that they might mate and produce offspring but there is surely no chance that the offspring could be fertile. Can anyone think of an example of a mammal (or indeed, vertebrate) where interspecific hybrids were fertile? The sort of thing that happens in plants but very rarely in animals ....
| You're right that it's rare, but it's not unheard of. As Deer Stalker has mentioned, Red & Sika can produce fertile hybrids (both species have 64 to 68 chromosomes), as can several canids (e.g. coyotes, domestic dogs and wolves), some ungulates (the infamous 'Beefalo' is a fertile hybrid between American buffalo and a domestic cow), reptiles and some wallabies. As far as I am aware -- and I'm happy for someone to correct me here --, hybrid sterility is often (always?) the result of a mismatch in the number of chromosomes, which prevents the animal producing functioning gametes.
Cheers,
Marc. |

If they did hybridise what do you reckon the result would look like?
Also bugs bunny was anthropomorphic so a hybridisation between a hare, a rabbit and a human! What was going through warner bros' minds????? | | | |
