Hi, so this question is regarding the goron -goro crater lion population, which is from the tanzania.
00:26
So we have to answer.
00:29
The major factors which were actually responsible for reducing the effective population size are different there are three of them and we have to select the correct options so first we can select option number b which is loss of genetic variation because this lion population was comparatively smaller than the large serengeti population and hence the genetic diversity was also much lower the next one we can select is option number d, which says lack of immigration.
01:22
Lack of immigration.
01:25
So it is seen that in earlier years, like 1962, in 1962, this population, crater alliance suffered some episodic, which actually was responsible for reducing the effective population.
01:45
Okay? so, additionally, seven males apparently immigrated into the greater land population, but no further immigration was there for at least 25 years.
02:05
So this is a major reason why the effective population was reduced...
