bithorax

A group of powerful pattern-generating genes called the bithorax complex, which is able to turn cell division off, is expressed at the proper time in the abdomen, and so, the authors tested its role in terminating abdominal neuroblast division.

Waddington noted that fruit flies expressed the odd trait of developing four wings the bithorax phenotype instead of two if they were exposed to ether early in development.

What Waddington did next was to select for individuals that expressed the bithorax phenotype most robustly, or that were better at resisting the ether, and found that he could get a progressive strengthening of the response.

Experiments 1 and 2 initially showed about 25 and 48% of the bithorax He phenotype.

Williams considers the question of whether the bithorax condition (resulting from direct artificial selection on that trait) should be seen as an adaptive trait, and his answer is that it should not.

Williams instead sees the bithorax condition as “a disruption ¦ of development,” a failure of the organism to respond (1966, pp. 75-78).
