Question

Explain why a population of Mouflon in the Indian Ocean descended from only two individual that had not experienced a loss of genetic diversity was so surprising to scientists.

Answer 1

The population of Mouflon in the Indian Ocean descended from only two individuals is surprising to scientists because it defies the traditional assumptions of genetic diversity and population viability. In general, populations that are founded by only a few individuals are expected to face a loss of genetic diversity over time, as there is limited genetic variation available in the initial gene pool. This loss of genetic diversity can lead to reduced fitness and increased susceptibility to diseases and environmental stresses, ultimately leading to a high risk of extinction.

However, in the case of the Mouflon population in the Indian Ocean, it was found that despite being founded by only two individuals, the population had retained a high level of genetic diversity over time. This was unexpected, as it suggests that the population was able to maintain a healthy level of genetic variation despite the limited initial gene pool. This finding challenges our assumptions about genetic diversity and population viability, and has important implications for conservation biology and the management of endangered species.
