Answer #1

MHC-Major histocompatibility molecules which are encoded gene polymorphic gene known in vertebrates. Pathogens play a key role in MHC-diversity. Low MHC is the result of selection of low Parasite diversity. In long term co-evolution, low diversity is caused by M.Incanus.Low MHC in diversity is caused by bottleneck events.

The species with low MHC diversity could have lost resistance alleles in such homogeneous population pathogens that will spread. Higher parasite loads are considered in this case.

Explain what diversity entails? We South African commonly refer to ourselves as the rainbow nation because our nation includes people of many different races, languages and religions. While we all share the important characteristics of the human species, biological and environmental differences separate and distinguish us as individuals and groups. This vast array of differences constitutes a spectrum of human diversity and causes us to perceive and interpret similar situations differently.
