The numbers in the table are the LSMEAN ± standard error of phenotypic value. The different superscript letters in the same column for each gene in lowercase represent significant level at p < 0.05, which letters in uppercase represent significant level at p < 0.01, and the same letter represents no significant difference (p > 0.05).1 B means FecB mutation; G means FecXG mutation; + means wild-type; C means FSHR g.47C>T mutation; T means wild-type.
