Sexuality is merely the personality trait that determines which gender someone is attracted to. Like being right or left-handed, the only biological difference that can be found is in the brain.
One study examined the brains of different deceased males and scientists often found a portion of the brain that was more developed in homosexual brains than in heterosexual. However, not all homosexual brains contained this difference, so while it correlates to homosexuality, it is not necessary for it to exist. Neurologists are learning more and more about the brain but how it relates to specific personality traits largely remains a mystery.

Technical replicates: measure quantity from 1 source. This measures the reproducibility of the results. The differences are based only on technical issues in the measurement. (I weigh myself three times, do I get different weights? How different?) Biological replicates: measure a quantity from difference sources under the same conditions. Tumors from 5 different people with lung cancer may show similar gene expression patterns. These replicates are useful to show what is similar in your replicates and how they are different from a different set of conditions (ie. treated, normal).
