The studies were conducted on 431 sheep (406♀ and 25♂) of three varieties of Polish lowland sheep: Żelazna sheep, corriedale sheep and Polish lowland sheep from the Podlasie region. All animals were subjected to the identification of the alpha-S1 casein gene – CSN1S1. On the basis of the research two alleles (C and T) and three genotypes (CC, CT and TT) were identified. A balanced frequency of alleles C and T in all investigated varieties was identified, which translated into a balanced distribution of genotypes: the T allele and the TT genotype occurred more frequently than C allele and CC and CT genotypes. There was significantly higher frequency of C allele and lower of T allele in ewes compared to rams in all studied varieties. The study concluded that in the frequency of alleles and genotypes of casein gene alpha-S1 in position 663 the genetic alignments in all three varieties of Polish lowland sheep were observed.
