Abstract
A simplified terminology is suggested for the description of experiments in which crosses are made between spp. having contrary systems of sex determination. It is proposed that X shall consistently indicate a sex chromosome having a ^-determining influence, and Y a sex chromosome having a [female]-determin-ing influence. So treated, Bellamy''s experiments indicate that in fishes the Drosophila type of sex determination is the original one and the poultry type a derivative of it attained by change of relative potency of X and Y. In the Drosophila type Y is more potent than X, in the poultry type X is more potent than Y.This publication has 1 reference indexed in Scilit:
