TABLE 1.
Phenotypic analysis of a sister-of-Sex-lethal null mutant allele
| Crossa | Genotype | % relative viability (no.) | % relative fecundityb (no. vs. control) | Control sibs for viability and fecundity determination |
|---|---|---|---|---|
| A | ssx−/ssx−♀ | 89 (940) | 102 (7 vs. 10) | +/ssx−♀ |
| A | ssx−/Y ♂ | 92 (913) | 76 (12 vs. 10) | +/Y ♂ |
| B | ssx+Rev/ssx−♀ | 97 (1075) | ND | +/ssx−♀ |
| B | ssx+Rev/Y ♂ | 96 (1031) | 90 (12 vs. 12) | +/Y ♂c |
| C | ssx−Sxl−/ssx− Sxl+♀ | 75 (376) | 96 (9 vs. 12) | ssx−Sxl−/ssx− +; Dp(Sxl+)/+♀ |
| C | ssx−Sxl−/ssx− Sxl+; Dp(Sxl+)/+♀ | 102 (504) | ND | Balancer/ssx−♀ |
| C | ssx− Sxl−/Y ♂ | 90 (462) | 139 (15 vs. 14) | ssx−Sxl−/Y; Dp(Sxl+)/+ ♂ |
| D | ssx− Sxl−/ssx+Rev +♀ | 85 (377) | 76 (11 vs. 11) | ssx−Sxl−/ssx+Rev +; Dp(Sxl+)/+♀ |
a
Full genotypes of crosses: (A) y ssx−55 w/+ ♀♀ × ♂♂ y ssx−55 w/Y; (B) y ssx+Rev26 w/+ ♀♀ × ♂♂ y ssx−55 w/Y; (C) Binsinscy/y ssx−55 w cm Sxlf1 ct; P[Sxl+w+mC]2A/+♀♀ × ♂♂ y ssx−55 w/Y; (D) same mothers as C × ♂♂ y ssx−+Rev26 w/Y.
b
Ratio of the median progeny recovered per parent to that for the control sibs.
c
In this one case, the controls for fecundity determination were cousins from cross A rather than sibs.
