microbov: Microsatellites genotypes of 15 cattle breeds

Description

This data set gives the genotypes of 704 cattle individuals for 30 microsatellites recommended by the FAO. The individuals are divided into two countries (Afric, France), two species (Bos taurus, Bos indicus) and 15 breeds. Individuals were chosen in order to avoid pseudoreplication according to their exact genealogy.

Format

microbov is a genind object with 3 supplementary components:

coun

a factor giving the country of each individual (AF: Afric; FR: France).

breed

a factor giving the breed of each individual.

spe

is a factor giving the species of each individual (BT: Bos taurus; BI: Bos indicus).
