Importance of Genetic Diversity
If a population consisted of identical individuals, dramatic changes in the environment would affect everyone in the same way, resulting in no variation in selection. Diversity in genes allows some individuals to perform slightly better than others when faced with environmental change.

Consider two isolated populations of a species. Population A exhibits a wide range of genetic differences among its members, while the individuals in Population B are genetically very similar to each other. If a novel and deadly disease emerges and spreads to both populations, which of the following outcomes is the most probable, and what is the underlying reason?
A researcher is comparing two pairs of siblings to understand the biological basis for differences in their psychological traits. Pair A consists of identical twins, who developed from a single fertilized egg. Pair B consists of non-identical (fraternal) siblings, who developed from two separate fertilized eggs. Why would the researcher expect to find a greater degree of genetic variation between the two individuals in Pair B compared to Pair A?
