Physical attraction linked to genes that control height
An analysis of the genotype of more than 13,000 human heterosexual couples found that genes that determine your height also influence your choice of mate by height.
Puberty timing influenced by both parents

Many genes, not just one influence sexual preference
Two of the five variants are common to both men and women, two are unique to men, and one was found only in women.
Genetic factors influencing sexual activity
Genetic variants associated with the age at which a person first engages in sexual intercourse are reported in a paper published online this week in Nature Genetics. The study sheds light on how the timing of puberty may affect age at first sexual intercourse (AFS), and how both affect social and health outcomes.
Study: Sexual Desire is in Your Genes
