L_3_09 — HLA Diversity and Immune System Evolution

The Human Leukocyte Antigen (HLA) system — the human version of the Major Histocompatibility Complex (MHC) found in all jawed vertebrates — is the most polymorphic gene region in the entire human genome. Located on chrom

L_3_14 — Genetic Bottleneck Recovery and Founder Effects

A genetic bottleneck occurs when a population's size is drastically reduced, causing a random loss of genetic variation (alleles) that cannot be recovered through subsequent population growth. Founder effects are a speci
