Genes, Vol. 15, Pages 260: FecB Was Associated with Litter Size and Follows Mendel’s Laws of Inheritance When It Transited to Next Generation in Suhu Meat Sheep Breeding Population Genes doi: 10.3390/genes15030260 Authors: Pengwei Su Yifei Gu Shanhe Wang Xiukai Cao Xiaoyang Lv Tesfaye Getachew Yutao Li Zhenghai Song Zehu Yuan Wei Sun In order to investigate the effect of FecB on litter size and growth and development traits of Suhu meat sheep and the inheritance patterns of FecB between parents and offspring in the population. In this experiment, 2241 sheep from the Suhu meat sheep population were tested for FecB using capillary electrophoresis. We combined the lambing records of 473 ewes, the growth trait records of 881 sheep at both the birth and weaning (2-month-old) stages, and the complete genealogical records of 643 lambs to analysis the distribution of FecB in the Suhu meat sheep breeding population, its effect on litter size of ewes, growth and development of lambs, and the inheritance patterns of FecB. The results showed that there were three genotypes of FecB in the Suhu meat sheep population, namely the AA genotype, AG genotype, and GG genotype. FecB in this population has a moderate polymorphism (0.25 < PIC < 0.5), and deviates from Hardy–Weinberg disequilibrium (p < 0.05). The litter size of GG genotype ewes was significantly higher than that with the AG and AA genotypes (p &am...
