Inbreeding: When Parents Transmit More Than Genes

Inbreeding: When Parents Transmit More Than Genes

Inbreeding in wild populations can have devastating effects on fitness, but the genetic causes should not be transmitted across generations. A new study of song sparrows has revealed a parent-offspring resemblance for inbreeding, resulting from population structuring, with important implications for understanding the genetic causes of phenotypic variation in wild populations.

Inbreeding parents should invest more resources in fewer offspring

Inbreeding increases parent-offspring relatedness and commonly reduces offspring viability, shaping selection on reproductive interactions involving relatives and associated parental investment (PI). Nevertheless, theories predicting selection for inbreeding versus inbreeding avoidance and selection for optimal PI have only been considered separately, precluding prediction of optimal PI and ass...
