Genetic Differences

Variations in the DNA sequences among individuals, which contribute to the biological diversity and hereditary traits within and across populations.

Fraternal Twins

Fraternal twins are siblings born at the same time as a result of two different eggs being fertilized by two different sperm, making them genetically similar to ordinary siblings rather than identical.

Identical Twins

Twins who develop from a single fertilized egg, sharing the same genetic material and typically having very similar appearances.

IQ Scores

Numerical measurements of intelligence, typically derived from standardized tests.
