backcross

Cascade, Mills Mess, Backcross and Tramline Pass are all terms used in which activity?

Thus, the Backcross (BC) 1 progenies already possess 75% of the abaca genome.

To date, samples from 25 individuals have been genotyped, including four putative first-generation (F1) hybrids, four putative second-generation grizzly bear backcross hybrids (GBC1), a female polar bear that was harvested in the company of two of the hybrids, and 16 grizzly bears that were sampled in the Arctic Islands to the north of the historic species range.

The favorable allele frequency of introgression QTL was shown in Table I, you can see flanking markers selection, introgression QTL frequency showed a downward trend with the increase of backcross generation.

Six foreground markers namely RM168, RM148, RM413, RM206, RM5961 and RM101 was found to be related to Pi-gene and used to evaluate F1 and each backcross generation.

The following results were obtained: (1) Genomic similarity selection and index selection can make recipient genome recover entirely through 3~4 backcross generations, though MBLUP selection could not make recipient genome recover quickly, it can get the most genetic responses for background traits.

Most of these studies focused only on the fitness of inter-specific and intraspecific F1 hybrids, whereas the effects of genetic mechanisms are, typically, most pronounced in F2 and backcross hybrids (Lynch 1991).

Triplody appeared in the backcross offspring from fauna carp crossing.

Schaible, with the approval of the Dalmatian Club of America's board of directors, was granted American Kennel Club (AKC) registration for two dogs from the fourth generation of the backcross. However, when the Dalmatian Club's general membership found out and caused an uproar, the AKC refused to register any offspring from these dogs.
