B3548 - Investigating the influence of natural selection on metabolites - 28/05/2020
Environmental and genetic factors both play a role in shaping individual variation. Characteristics that increase an individualâs chance of survival and reproduction are more likely to be passed onto the next generation. This process is known as natural selection and it is reflected at the genetic level. Negative selection is a form of natural selection whereby rare genetic factors with harmful effect on survival and reproduction are removed from populations. Recent studies have found evidence of negative selection acting on complex traits such as body mass index (BMI), blood pressure and height.
This project will explore how natural selection influences molecular traits. Metabolites are intermediates or end products of biological processes and they are linked to numerous diseases. Gaining a better understanding of how metabolites are related to survival and reproduction will enable researchers to prioritise specific research avenues. This prioritisation may improve human health.
