Table 1. Phenotypes of male y w and dmP0 mutant flies carrying a pont and/or rept mutation.
| Genotype | Viability, % | Development, days | Weight, μg |
|---|---|---|---|
| y w/Y;+/+ | 98 (339) | 10.3 ± 0.6 (339) | 863 ± 56 (47) |
| y w/Y;pont–/+ | 108 (281) | 10.1 ± 0.6 (281) | 854 ± 37 (27) |
| y w/Y;rept–/+ | 92 (487) | 10.0 ± 0.5 (487) | 828 ± 44 (44) |
| y w/Y;rept–/+pont–/+ | 108 (363) | 10.1 ± 0.4 (363) | 852 ± 46 (33) |
| dmP0/Y;+/+ | 54 (287) | 10.6 ± 0.4 (287) | 772 ± 53 (46) |
| dmP0/Y;pont–/+ | 12 (55) | 13.0 ± 0.8 (55) | 693 ± 65 (21) |
| dmP0/Y;rept–/+ | 60 (301) | 10.8 ± 0.4 (301) | 774 ± 33 (29) |
| dmP0/Y;rept–/+pont–/+ | 20 (81) | 12.4 ± 0.7 (81) | 702 ± 70 (25) |
Viability is calculated as the percentage of the total of the expected genotype. Development indicates the time from egg deposition until eclosion. Values differing significantly (P < 0.01) from their control (dmP0/Y;+/+) are shown in bold. Standard deviations were calculated based on the total number of animals reported (indicated in parentheses). None of the y w/Y genotypes differed significantly from y w/Y;+/+. Note that relevant comparisons can only be made within the dm+(y w) and the dmP0 flies, because the two lines are not isogenic.
