You are studying a region of the genome on chromosome 11 that contains several hemoglobin genes and their associated cis-regulatory modules (CRMs). These CRMs are DNA elements where proteins can bind to regulate expression of the hemoglobin genes. These genes are expressed at different times during development. HBB and HBD are expressed in adults, HBG1 and HBG2 are expressed during fetal development, and HBE1 is expressed during embryonic development. GATA1 is a transcription factor expressed in blood cells. What evidence (if any) does not support the hypothesis that CRM B has a function associated with it

Hypothesis: the smell of decomposing apples may attract fruit flies more than the smell of decomposing bananas.

Experiment: two separated fruit fly populations with a sample size statistically significant (N: 500 or higher) must be grown in clean boxes. Subsequently, the fruit fly populations should be simultaneously released in a tube that connects the two boxes with other two boxes containing: -Box 1: apples in decomposition and -Box 2: bananas in decomposition. After one hour, the fruit boxes must be simultaneously closed and the fruit flies must be counted. Finally, it is necessary to apply a statistical index in order to calculate the significance between groups (i.e., fruit flies closed in both fruit boxes).

Positive control: fruit flies released and counted in boxes containing apples and bananas in normal conditions.  

Negative control: fruit flies released and counted in clean boxes.
