Genomic imprinting violates the usual rules of Mendelian expression in a diploid individual by privileging the expression of one of the two copies of a gene, depending on its parental origin. The ...

Common misconceptions of the ‘parental conflict’ theory of genomic imprinting are addressed. Contrary to widespread belief, the theory defines conditions for cooperation as well as conflict in ...

Using modern genetic approaches, a team of researchers has provided strong support for the long-standing, but hotly debated, evolutionary theory of kin selection, which suggests that altruistic ...
