nancycats: Microsatellites genotypes of 237 cats from 17 colonies of Nancy (France)

Description

This data set gives the genotypes of 237 cats (Felis catus L.) for 9 microsatellites markers. The individuals are divided into 17 colonies whose spatial coordinates are also provided.

Usage

data(nancycats)

encoding

UTF-8

format

nancycats is a genind object with spatial coordinates of the colonies as a supplementary components (@xy). Beware: these coordinates are given for the true names (stored in @pop.names) and not for the generic names (used in @pop).
