Crossmate

They proved to be fertile when they were crossmated and backcrossed to both parental species (using the forced-copulation method).

If Jondalar and Ayla would stay and become Sharamudoi, we would make an offer to cross-mate with them, but since Markeno and I are Ramudoi, they would have to be Shamudoi.

Both Aberdeen Angus and Hereford cows also have a different average length of gestation when purely mated than when crossmated.

Indeed, the results available so far from crossbreeding experiments show an overall positive effect of crossmating straightbred cows.
