Professor Nina Wedell | Hidden Conflict Between Sexes Maintains Genetic Diversity

Apr 10, 2024 | biology

About this episode

Far from being harmonious, the reproductive relationship between males and females is full of conflict. Differing optimal states for traits shared between the sexes leads to unseen conflict within the very molecular blueprint for life – the genes. Sexual conflict arising in certain alleles – alternative forms of a gene – could help to maintain genetic variation in populations. Research aiming to characterise this process of balancing selection is fundamental to our understanding of evolution. However, the theory has attracted controversy, because specific alleles producing sexual antagonistic selection have not been identified in natural populations… until now. Read More
