Question

How has molecular genotyping changed human mating in terms of sexual selection? (Evolutionary biology course PLZ answer it in a broad and clear way. Thank you!)

Answer 1

Molecular genotyping is the finding the genotype of an organism with the help of individuals DNA sequence. It refer to the allele that are present in male or female . Molecular genotyping in human is performed by the specific genomic region. Like Single nucleotide polymorphism are used in human molecular genotyping.  

This genotyping is used to find the traits in male and female that are important for the sexual selection. There is always a competition between male and male, and between female and female, in order to choose best mating partner, so that their successive generation are having best allele from both the parent.  

Trait are selected so that they can resist different environmental conditions, so that are frequently selected for mating, hence are selected for sexual selection.
