Maternal Transmission Ratio Distortion in Two Iberian Pig Varieties. [PDF]

open access: yesGenes (Basel), 2020
Transmission ratio distortion (TRD) is defined as the allele transmission deviation from the heterozygous parent to the offspring from the expected Mendelian genotypic frequencies. Although TRD can be a confounding factor in genetic mapping studies, this phenomenon remains mostly unknown in pigs, particularly in traditional breeds (i.e., the Iberian ...
