B. Freeman et al., DNA BY MAIL - AN INEXPENSIVE AND NONINVASIVE METHOD FOR COLLECTING DNA SAMPLES FROM WIDELY DISPERSED POPULATIONS, Behavior genetics, 27(3), 1997, pp. 251-257
As specific genes are identified that are associated with behavior, it
becomes increasingly important for behavioral geneticists to be able
to incorporate these genes in their research. Rather than using blood,
DNA can be extracted from cheek swabs, which makes it possible to obt
ain DNA inexpensively by mail from large, widely dispersed individuals
. The purpose of this paper is to recommend this technique to the beha
vioral genetics community and to present results of our use of this te
chnique to obtain DNA by mail for 114 2-year-olds and 116 adults.
