Evolutionary biology: Genetics and bisexuality
Vincent Savolainen1 & Laurent Lehmann2
Abstract
A population-genetic model indicates that if there is a gene responsible for homosexual behaviour it can readily spread in populations. The model also predicts widespread bisexuality in humans.
For human societies at large, homosexuality is a sensitive issue. For biologists it is an intriguing one1, 2.
