How quantitative is metabarcoding: A meta-analytical approach.

abstract：:Molecular techniques have enabled behavioural ecologists to reassess mating systems from a genetic perspective. Studies of paternity frequently reveal that mating behaviour does not always reflect parentage, and may bring to light alternative mating tactics. Here we present a comparison of behavioural and genetic meas...

abstract：:Variation in social behaviour is common, yet little is known about the genetic architectures underpinning its evolution. A rare exception is in the fire ant Solenopsis invicta: Alternative variants of a supergene region determine whether a colony will have exactly one or up to dozens of queens.

The size of a clone, however, might be largely determined by physical or biotic interactions, obscuring the relationship between clone size and age.
