Phenotypic distribution of embryos laid by dsh/ovoD1;;nkd/+ females (♀) mated to +/Y;;nkd/TM3 males (♂; see Materials and Methods for details). Four cuticular phenotypes were expected: wild-type (wt), dsh, nkd and unknown corresponding to the dsh; nkd double mutant, with ratios of 3:8 (37.5%), 3:8 (37.5%), 1:8 (12.5%) and 1:8 (12.5%), respectively. Two dsh alleles (dshv26, dsh477) and two nkd alleles (nkd7H16, nkd7E89), all strong alleles, were used in different combinations, as indicated in the first column. Results are presented as percentages followed between parentheses by the observed number of embryos (first number) and the expected number (second number). A total of 1305 embryos were counted and the total percentage for each phenotype is indicated in bold.
