A high degree of genetic homogeneity in a population may increase susceptibility to an infectious disease.

Question

Quizplus · Accepted Answer

A high degree of genetic homogeneity in a population means that there is less variation in the genes that control the immune system, making the population more vulnerable to infectious diseases. This is because a pathogen can easily spread through the population and infect a large proportion of individuals who all have similar immune responses. In contrast, in a population with greater genetic diversity, some individuals may have immune responses that are more effective against the pathogen, reducing the overall impact of the disease.
