Given the importance of sexual reproduction to the survival of a species, why do human SRY genes function so close to the boundary of infertility? |
Male development of chromosomally female mice transgenic for Sry. |
He speculates that the SRY protein might suppress genes required for female development, or activate genes whose products add up to maleness. |
When such an X chromosome contributes to the child, the development will lead to a male, because of the SRY gene. |
In mammals, the Y chromosome contains the gene SRY, which triggers testis development. |
In mammals, the Y chromosome contains a gene, SRY, which triggers embryonic development as a male. |
