How does MHC affect mate choice?

Although it has not been established that odor preference is a key factor in mate choice, such studies support the hypothesis that humans are able to discriminate MHC types of potential mates through odor cues and that humans may use such information when choosing a mate.

What are the 3 different MHC classes?

The MHC gene family is divided into three subgroups: MHC class I, MHC class II, and MHC class III. Among all those genes present in MHC, there are two types of genes coding for the proteins MHC class I molecules and MHC class II molecules that are directly involved in the antigen presentation.

What is the function of MHC?

The function of MHC molecules is to bind peptide fragments derived from pathogens and display them on the cell surface for recognition by the appropriate T cells.

What is MHC genotype?

Introduction. The major histocompatibility complex (MHC) genomic region consists of a large group of evolutionary-related genes involved functionally with the innate and adaptive immune systems in jawed vertebrates [1]. In humans, the MHC is located on the short arm of chromosome 6, band p21.

What is the major histocompatibility complex MHC and how is it important for choosing mates?

Specific pathogen recognition is mediated by genes of the major histocompatibility complex (MHC) encoding proteins fundamental for adaptive immune response in jawed vertebrates. MHC genes may also play a role in odour-based individual recognition and mate choice, aimed at avoiding inbreeding.

What is mhc1 and mhc2?

MHC class 1 and 2 are two types of surface antigens involved in the development of adaptive immune responses against non-self. MHC class 1 molecules present endogenous antigens to cytotoxic T cells. MHC class 2 molecules present exogenous antigens to helper T cells.

Why is the major histocompatibility complex?

major histocompatibility complex (MHC), group of genes that code for proteins found on the surfaces of cells that help the immune system recognize foreign substances. MHC proteins are found in all higher vertebrates. In human beings the complex is also called the human leukocyte antigen (HLA) system.
