In addition to the combinations of eosin and vermilion, sable also appeared in its proper distribution though no counts were made. The four smaller classes are cross-overs between eosin and vermilion. Since no "pinks" appeared the color is recessive, and the brother was not heterozygous for it.
Two other "pink" females mated to wild males gave similar results in their sons.

These F1 flies should all be heterozygous for "pink." A pair of wild-type flies which were mated gave a 3 : 1 ratio—wild type 51 to "pink" 18. From the "pinks" which appeared in this cross a stock was made which was lost through sterility. Females tested to males of true pink were also sterile, so that no solution can be given of the case.
[6] Purple is an eye-color whose gen is in the second chromosome.
[7] The curve published by Miss Stark included by mistake 6 cultures from the succeeding generations, and these coming from only one of the lethals (lethal sb) increase its mode so that the mode of the other lethal (lethal sa) becomes submerged. If these cultures are taken out the curve shows two modes more clearly.
[8] The figures to the left in each double column correspond to the symbols above the heavy line, as, in the first example 6,219 white miniature. The similar figure to the right corresponds to the symbol below the heavy line. If no symbols are present below, as in the first example, the column to the right should be read wild-type.
