The choice of a future partner may be genetically determined. American researcher Gretchen Sunders reached this conclusion after analyzing more than 80,000 \"personal files\" of existing married couples. When she studied the data, Sunders noted the DNA versions of the partners. According to the findings, the traits that provide the most matches are height and body mass index. Characteristics such as education level and attitude toward alcohol often overlap in stable couples, but are less \"programmed\" at the genetic level. However, the scientist warns: genes cannot completely determine who a person will fall in love with during their life – lifestyle and environment have a greater influence.
