In the case of homosexuality we potentially are talking about randomly occurring variations of a a specific gene that would seem to occur with regularity.

«Identifying which of these candidate genes actually causes variation in responses to cold snaps will give us the potential to understand whether evolution to climate change can occur in both wild and domesticated animals, allowing us to better predict which species or breeds will be «winners» and «losers» and to better mitigate the effects of anthropogenic climate change on a wide range of organisms from beneficial pollinators to invasive pests,» said Theodore Morgan an associate professor of evolutionary genetics in the Division of Biology at Kansas State University and senior author of the study.

The scientists looked for mutations, or abnormal changes in the DNA, and filtered out normal variations in genes that commonly occur among humans.

By studying rare «copy number variations,» which are individual errant insertions or deletions of DNA segments (each of which occur in less than one percent of the population), researchers discovered a new cluster of genes that are affected in some autistic individuals as well as a number of mutations that were present in autistic children but not their parents.

«While previous molecular studies have provided simple snapshots of the gene transcript variations that are associated with the exposure of insects to natural and synthetic chemicals, the genomics approaches used in this study offer a significantly more complex perspective on the biochemical and physiological processes occurring in plant - insect interactions,» Schuler said.

Correlation of gene expression occurred across lean and obese mice, defining a common transcriptional response to variations in adiposity.

«Gene variations occur naturally, and may become common in a population if they convey a health benefit,» said Douglas Bell, Ph.D., author on the paper and researcher at the National Institute of Environmental Health Sciences (NIEHS), part of NIH.

In the course of this work, he has pioneered several new approaches in the fruit fly that have had important implications for mammalian neurobiology, including: the demonstration that the fruit fly has a sleep - like behavior similar to that of mammals, studies of physiological and behavioral consequences of mutations in a neurotransmitter system affecting one of the brain's principal chemical signals, studies making highly localized genetic alterations in the nervous system to alter behavior, and molecular identification of genes causing naturally occurring variation in behavior.

Each of the three trace amine - associated receptor genes can occur in two variations in each individual.

The researchers then zeroed in on the gene variations that occurred more often in the people with bipolar disorder and examined them individually.
