Effect of the AA-NAT SNP on reproductive traits in Egyptian sheep breeds in their first conception season. Where $N$ is the number of observed genotypes; LSM represents least-square mean; SE represents standard error; LF represents late favorable season; UF represents unfavorable season; EF represents early favorable season.
