Chapter 1, Problem 19RA
Summary Introduction
To review:
The consequences of maintenance of physiological regulatory mechanisms by positive feedback rather than by negative feedback.
Introduction:
The feedback mechanism in biology allows the living organism to respond against the changes in the surroundings. Feedback loops can either increase or decrease the change. If an output amplifies the change in a system producing it, it is called a positive feedback loop. If an output reduces the input then it is known as a negative feedback loop.

Three of the many recessive mutations in Drosophila melanogaster that affect body color, wing shape, or bristle morphology are black (b) body versus grey in wild type, dumpy (dp), obliquely truncated wings versus long wings in the male, and hooked (hk) bristles versus not hooked in the wild type. From a cross of a dumpy female with a black and hooked male, all of the F1 were wild type for all three of the characters. The testcross of an F1 female with a dumpy, black, hooked male gave the following results:
