TDY
{ 1 } - differentiate at seven weeks in embryonic development if the Y chromosome is present
{ 2 } - sexual ducts that are present in all embryos but that develop into male structures (epidydimis and vas deferens) if the Y chromosome is present

{ 4 } - the presence or absence of which in the one cell zygote that biological determination of sex depends on
{ 5 } - are destroyed if the Y chromosome is present in the embryo
