WebThe F 1 animals obtained from this outcross can be used in two types of crosses commonly performed by mouse geneticists — backcrosses and intercrosses. A mating between a heterozygous F 1 animal (with an A/a genotype) and one that is homozygous for either the A or a allele is called a backcross. This term is derived from the vision of an F 1 ... WebThere were significant differences among the performance of the backcross lines for agronomic traits; however, yield performance for most of the backcross lines did not significantly differ from the recurrent parent.
