Question

In the case of the Florida panther, a severe genetic bottleneck has resulted in reproductive difficulty for the panthers, with many males having low sperm count and abnormal sperm. Why don't scientists reintroduce genetic diversity back in to the population? Select all that apply. Choose one or more: A. Scientists are reintroducing diversity through a comprehensive breeding program. B. The original and ultimate source of diversity is mutation, which cannot be safely recreated by scientists for the Florida panther. C. Scientists can try to reintroduce genetic diversity, but it will not be successfully established in the population without successful reproduction. Since the panthers have reproductive problems, successful reproduction is difficult. D. When the panthers died off almost to extinction, most panther genetic diversity died with those individuals who carried it in their DNA. Therefore, there is no available genetic diversity to reintroduce.

Explanation / Answer

1. Scientist can reintroduce diversity but due yo their incompatibility to reproduce diversity can not be maintained.

Also with the dying of pathers diversity is being lost continously.

Option c and d are correct.

2. Option D is correct. Fish species are incompatible for fertilazation of gametes and no zygote is formed at all. And is an example of prezygotic barrier.
