Gray wolves have been crossed with dogs that have a wolf-like appearance, such as backcrossed to domestic dogs to maintain a domestic temperament and consistent conformation.
12.
Loss of hybrid vigour occurs and phenotype varies greatly in subsequent generations if F1 hybrids are inter-bred or backcrossed with animals genetically similar to the F1 parent.
13.
The resulting offspring were then backcrossed repeatedly with Cornflower Blue plants until the horticulturists were satisfied that they had stabilized a new strain of 12-inch tall blue cineraria.
14.
In a species with two pairs of chromosomes, a twice backcrossed individual would be predicted to contain 12.5 % of one species'genome ( say, species A ).
15.
Developed by the International Rice Research Institute, the backcrossed to IR56 with the aim of preserving the genes responsible for salt tolerance that were inherited from " O . coarctata ".
16.
On investigation, it turned out to be an offspring of a hybrid between a female of that species and a male masked spinefoot, which had successfully backcrossed with the blue-spotted spinefoot.
17.
Without fossil evidence of other ancestral species between the steppe bison and the European bison, though the European bison might have arisen from the lineage that led to American bison if that lineage backcrossed with the steppe bison.
18.
While it is possible to predict the genetic composition of a backcross " on average ", it is not possible to accurately predict the composition of a particular backcrossed individual, due to random segregation of chromosomes.
19.
In gene knockout experiments in particular, where the knockout is performed on easily cultured stem cell lines, but is required in an animal with a different genetic background, the knockout animal is backcrossed against the animal of the required genetic background.
20.
The European bison arose from the steppe bison, without fossil evidence of other ancestral species between the steppe bison and the European bison, though the European bison might have arisen from the lineage that led to American bison if that lineage backcrossed with the steppe bison.
