In likely has an insert

--Peter A. Peterson

Geneticists have long noticed the appearance of colored sectors involved with C-I in the genotype C-I C C. Whether those colored spots are due to the spontaneous loss of C-I or the occasional loss of the insert now known to be in C-I, has not been verified. Now with In, colored sectors often appear in numerous crosses of c2 in/c2 in x c2 In/c2 In. The expected phenotype from this cross is colorless. If a change occurs in In (to in?), colored (pale) sectors would appear. It will be interesting to see what the In gene status is when In is finally isolated and analyzed.
