ALTERING SEX RATIO OF OFFSPRING IN MAMMALS

摘要

Methods of altering sex ratios in mammalian populations by treating pregnant female mammals (P generation) with hormones or anti-hormones are described. The sex ratio of the F1 generation born to treated mammals exhibits a normal sex ratio, but the sex ratio of the F2 generation is altered depending on the active agent given to the pregnant dam. Administration of androgens to the P generation dam results in an F2 generation with more males than would be expected in the absence of treatment; administration of an anti-androgen results in more females.
