From these results we know that //ic S-Y coupling in the male gametic 
series zvas neither on j : i : i : j nor] on ^ : i : i : but it follows 
either j .•/.•/.• j or 2:1:1:2 system.

Thus it is evident that a complete repulsion occurs in the female gametic 
series. 
The results abo\'e described brought to light the gametic series in 
SsYy animal (into which S and Y were introduced by the same parent). 
They do not follow the same system of the reduplication in male and 
female, but they distinctly differ from each other, namely:
