The Enterоbаcteriаceаe have the fоllоwing common characteristics:
A Nоtch mutаtiоn wаs determined tо be а deletion on the X chromosome of Drosophila melanogaster. Female flies heterozygous for Notch have a notched wing phenotype. Notch is lethal in the homozygous or hemizygous conditions. This deletion is relatively large and also deletes the white gene, which is involved in eye pigmentation in flies. The w+ allele is dominant and gives flies the wildtype red eye phenotype and the mutant form, w, is recessive and leads to a white eye phenotype. If you cross a red-eyed Notch female to a red-eyed normal-winged male, what would be the proportion of each phenotypic group listed below. Fill in zero for any group that you would expect to not see in the F1 generation (including any phenotypic group containing a lethal combination of Notch alleles). White-eyed females with notched wings White-eyed females with wildtype wings Red-eyed females with notched wings Red-eyed females with wildtype wings White-eyed males with notched wings White-eyed males with wildtype wings Red-eyed males with notched wings Red-eyed males with wildtype wings
