Unlike humans, the sex and physical appearance of fruit flies is not influenced by hormones. [16] The appearance and sex of fruit flies is determined only by genetic information. [16] Female fruit flies are substantially larger than male fruit flies, with females having bodies that are up to 30% larger than an adult male. [17] [18]
Drosophila embryogenesis, the process by which Drosophila (fruit fly) embryos form, is a favorite model system for genetics and developmental biology. The study of its embryogenesis unlocked the century-long puzzle of how development was controlled, creating the field of evolutionary developmental biology . [ 1 ]
A metafemale (or superfemale) is a low viability Drosophila fruit fly with a female phenotype in which the ratio of X chromosomes to sets of autosomes (A) exceeds 1.0. [1] For example: a fly with one X chromosome and two sets of autosomes is a normal male, a fly with two X chromosomes and two sets of autosomes is a normal female, and a fly with three X chromosomes and two sets of autosomes (or ...
“The reproductive potential of fruit flies is enormous; given the opportunity, they will lay about 500 eggs. The entire life cycle from egg to adult can be completed in about a week,” he wrote.
A metamale (or supermale) is a low viability Drosophila fruit fly with a male phenotype in which the ratio of X chromosomes to sets of autosomes (A) is less than 0.5. [1] For example: a fly with one X chromosome and two sets of autosomes is a normal male, a fly with one X chromosome and three sets of autosomes is a metamale.
The Drosophilidae are a diverse, cosmopolitan family of flies, which includes species called fruit flies, although they are more accurately referred to as vinegar or pomace flies. [1] Another distantly related family of flies, Tephritidae , are true fruit flies because they are frugivorous, and include apple maggot flies and many pests.
