You didnt choose the parents for the F1 cross to achieve your objective, and you dont know the parents characteristics, so the phenotypes that you get from dehybridizing are anyones guess. 6 b). True breeding means that no matter how many times a cross is performed, identical phenotypes will occur each time. Giventhe popular breeding strategies employed today, there has been a rise in inbreedingtherefore inbreeding depression within flocks and groups of livestock.

Although the offspring do not match either parent directly, all offspring do show the dominant phenotype. One of the main benefits of crossbreeding is that there is a reduction in inbreeding, which also leads to hybrid vigor, as explained earlier. In a zoo, a female tigon mated with an Asiatic lion.

Cross- breeding Mating of superior male of one breed and superior female of another breed is called cross breeding. This process is called dehybridizing because you are starting with a hybrid, but after several generations of production, selection, and seed saving you are creating new pure lines from that hybrid. Presently, there is a need to conduct longer and more rigorous research studies to understand the effects of crossbreeding in subsequent generations. The strategies for the two plants differ because of how the final plant will be propagated. This is called a reciprocal cross.
