Human Fertilization Process
The process that initiates genetic variation in humans begins with ovulation, when an ovary releases an egg about once a month. This egg travels through the fallopian tubes towards the uterus, and during this journey, it can be fertilized by a sperm.

Traits
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?
