Es un organismo dioico, es decir, que presenta sexos separados. Adicionalmente, presenta dimorfismo sexual. Hembra y macho de Drosophila melanogaster. Tomada y editada de: Madboy74 [CC0]. Sin embargo, su longevidad puede variar dependiendo de las condiciones ambientales, principalmente por la temperatura del medio donde se encuentre.
Estos investigadores, de la Universidad de Columbia EE. El medio de cultivo que empleaban Morgan y sus colaboradores para mantener las moscas eran botellas de leche. En cualquier caso, las moscas de la fruta pertenecen al orden Diptera, suborden Brachycera y a la familia Drosophilidae. La especie D. En cambio, el gen mutante de las alas curvadas es dominante, sin embargo, solo se manifiesta cuando el portador es heterocigoto, pues los homocigotos no son viables.
Mutaciones en los ojos Los ojos de la mosca de la fruta normal son de color rojo. En este caso, las moscas se desarrollaran hasta la edad adulta, pero sin ojos. Desarrollo anormal de antenas Mutaciones en el gen que codifica el desarrollo de las antenas pueden ocasionar, eventualmente, que en lugar de las antenas se desarrollen un par de patas en la cabeza.

Learn how and when to remove this template message D. That is, with sexual experience, these flies tend to modify their future mating behavior in multiple ways. These changes include increased selectivity for courting only intraspecifically, as well as decreased courtship times. However, after D. This apparent learned behavior modification seems to be evolutionarily significant, as it allows the males to avoid investing energy into futile sexual encounters. Polygamy[ edit ] Both male and female D. The difference in evening activity between polygamous and monogamous male flies can be explained with courtship.
