Kinship
Definition
Biological relatedness that can make collected insects non-independent samples of a regional population. Larvae from one resource can share parents or other close relationships. Treating many siblings as independent observations can distort reference frequencies or apparent assignment performance.
- Context
- Population sampling
For example, twenty larvae from one egg batch may provide much less independent population information than twenty unrelated insects sampled across locations.
Sampling design should address that dependence.
