The agency saw no problems with the safety of the conventionally bred offspring of clones.
And whatever those genetic abnormalities are, it said, they are not passed on to the conventionally bred offspring of clones.
The agency issued a draft report last year declaring that the milk and meat from cloned animals and their conventionally bred offspring were safe to eat.
In June 2001, the agency asked cloning companies and farmers to keep off the market voluntarily the milk and meat from clones, and from the more conventionally bred offspring of clones, so it could assess the potential risks.
Males with larger repertoires had chicks that were heavier at fledging, and more of these chicks survived to breed than offspring of males with smaller repertoires.
Mice then kept on low-fiber food and allowed to breed produced offspring with an even lower diversity, the team reports online today in Nature.
As a result, when two animals from the same RI mouse strain are bred, their offspring will have the exact same genetic makeup (i.e., genotype) as the parents.
In response, some breeders have crossed Hog Island sheep with other breeds, including Gulf Coast Native sheep, and then bred the offspring with pure Hog Island sheep, producing almost pure Hog Island sheep except for the addition of some genetic diversity.
We bred F1 offspring of wild-caught mice to produce 12 litters that had at least two female and two male offspring.
During intensive breeding of Q76 mice, however, we unexpectedly found a mosaic mouse harboring largely expanded CAG repeats (Q129), in addition to the 76 repeats from progenitor mice, which bred transgenic offspring carrying 129 CAG repeats exhibiting distinct behavioral abnormalities.
