Approaching autozygosity in a small pedigree of Gochu Asturcelta pigs
Genetics Selection Evolution, 2023 Background In spite of the availability of single nucleotide polymorphism (SNP) array data, differentiation between observed homozygosity and that caused by mating between relatives (autozygosity) introduces major difficulties.
