Answer:
The founder effect may result in a population with a diminished gene pool, so there is a need to choose organisms with diverse genetic material.
In order to reduce the loss of any allele, preferential mating must be made between the organisms possessing rare alleles.
Inbreeding leads to reduced fitness as inbreeding occurs because of mating between the associated individuals, thus, there is a need to permit the least associated individuals to mate.
The captive-bred animals may exhibit reduced adaptation in wild, thus, they must be discharged into the wild prior passing of the generation.
The loss of learned behavior is generally associated with the acquired trait and does not associate much with genetics.
Meiosis increases genetic variation due to random segregation which occurs.
In anaphase I of meiosis, the homologous pairs (one maternal and one paternal chromosome) are moved apart to opposite ends of the cell and this process occurs random. This allows the formation of gametes with different sets of homologues. In this phase sister chromatids remain attached at their centromeres (not segragated as in mitosis).
