backcross /ˈbakkrɒs/Genetics verb [with object]Cross (a hybrid) with one of its parents or an organism with the same genetic characteristics as one of the parents: (as adjective backcrossed) after five generations the backcrossed dogs were indistinguishable from pure-bred Dalmatians...- The parent cultivars were crossed to produce an initial hybrid that was then backcrossed to each parent.
- To eliminate possible additional mutations, the mutant strains were backcrossed eight times before genetic analyses.
- Each candidate was then backcrossed to the unmutagenized parent and tetrads were dissected to ensure that the synthetic lethal phenotype resulted from a single mutation.
nounAn instance or result of backcrossing.However, after several backcrosses, its heterozygotes could be distinguished from the dominant homozygotes....- Genetic backcrosses were conducted to eliminate plasmid-based mutations and to verify that a single genetic locus was responsible for the 3 - AT-resistant phenotype.
- After 10 backcrosses into the NIH433a genetic background, both KN433a and KN433 were identical to each other and to NIH433a at all markers examined except those in the MAT locus.
