Association between litter size and the k-casein genotype in the INRA rabbit lines

[EN] The reproductive traits of 276 rabbit does belonging to an intercross generation of two synthetic INRAlines, which differed by their genotypes at the k-casein locus being either AA or AB, were recorded at birth andat weaning for a total of 743 litters. They were the daughters of 77 dams whose k...
