No one can answer whether nature or nurture leads to certain traits in individuals. We do know, however, a bit about the influences of genes and the environment when it comes to groups of specific populations — especially when we talk about us humans. Our understanding of little asexual crayfish seems rather limited.

In particular they look at two forms of twin studies. Non-identical twins who are raised in the same family — they experience a similar environment, but just like most siblings share 50% of their DNA. Identical twins who are raised in different families: In these rare instances, the twins share the same genes (in fact not all identical twins share the same genes), but were given up for adoption at birth and are therefore raised in completely different environments.
