ONKI3 | Medical Subject Headings

The ONKI is provided as a part of the ONKI Living Lab - an open lab for testing the latest semantic web technologies in practice, with real users like you. Currently, over 10 000 people are using ONKI each month.

We hope you like the ONKI service and enjoy using it for your purposes!

If you encounter any problems or have improvement ideas, please contact the ONKI team. We are also very much interested in your success stories in using ONKI - please share your experiences!

Annotation:	an epidemiol technique for study of twins: do not confuse with articles on TWINS as persons or on specific or general DISEASES IN TWINS; IM GEN only; coord NIM with specific subject (IM) + TWINS (IM) or with specific dis (IM) + DISEASES IN TWINS (IM); do not confuse with Publication Type TWIN STUDY X

Scope note:	Methods of detecting genetic etiology in human traits. The basic premise of twin studies is that monozygotic twins, being formed by the division of a single fertilized ovum, carry identical genes, while dizygotic twins, being formed by the fertilization of two ova by two different spermatozoa, are genetically no more similar than two siblings born after separate pregnancies.
