Vedclass · Answer

(C) Change in population density provides insight into whether a population is increasing or declining. Population density is influenced by natality,mortality,immigration,and emigration. In an isolated small tribal population,if individuals marry only within their own tribe,it leads to a restricted gene pool. Over time,this practice increases the frequency of homozygous recessive traits,including hereditary diseases. Furthermore,such isolation often leads to a decline in population due to reduced genetic diversity and potential reproductive barriers,ultimately resulting in a decrease in the population size.
