Caption: Different species of fruit flies exhibit remarkably different patterns of wing decoration. At the top is the familiar Drosophila melanogaster, the workhorse model organism of genetics, which differs markedly from other fruit fly species. Exploring a single gene that controls pigment deployment in fruit flies, a group led by UW-Madison biologist Sean Carroll has found the molecular switches that control where the pigmentation is deployed on the wing. The finding explains how common genes can be controlled to produce the seemingly endless array of patterns, decoration and body architecture found in animals.

Digging deep into a single gene that produce pigmentation in the flies, a group led by UW-Madison biologist Sean Carroll has found the molecular switches that control where the pigmentation is deployed. The finding explains how common genes can be controlled to produce the seemingly endless array of patterns, decoration and body architecture found in animals.

Caption: Behaving like some human males at a singles bar, the male fruit fly in this movie is showing off his wing spots in an effort to get the attention of the ladies. The wing spots are found only on male fruit flies, and the number and patterns of spots on the wings of different species varies greatly. A team at UW-Madison led by biologist Sean Carroll has found the molecular switches that control where the pigmentation is deployed on the wing. The finding explains how common genes can be controlled to produce the seemingly endless array of patterns, decoration and body architecture found in animals.

Caption: Nicolas Gompel, postdoctoral fellow in molecular biology, uses a sweeping net to catch fruit flies in the University Housing community garden. Gompel researches the genes that drive differences in pigmentation in fruit flies (genus Drosophila), using flies caught in his apartment and around the University Housing community garden compost heap.
