Human genetics

The genetic history of indigenous peoples of the Americas primarily focuses on Human Y-chromosome DNA haplogroups and Human mitochondrial DNA haplogroups.

A dimple (also known as a gelasin) is a small natural indentation in the flesh on a part of the human body, most notably in the cheek or on the chin.

Phenylthiocarbamide (PTC), also known as phenylthiourea (PTU), is an organosulfur thiourea containing a phenyl ring.

Clinodactyly /ˈklaɪnˌoʊdæktɪli/ (from the Ancient Greek κλίνειν klínein meaning "to bend" and δάκτυλος dáktulos meaning "digit") is a medical term describing the curvature of a digit (a finger or toe) in the plane of the palm, most commonly the fifth finger (the "little finger") towards the adjacent fourth finger (the "ring finger").

The study of the genetics and archaeogenetics of the ethnic groups of South Asia aims at uncovering these groups' genetic history.

Consanguinity ("blood relation", from the Latin consanguinitas) is the property of being from the same kinship as another person.

<section begin=lead />The human genome is the complete set of nucleic acid sequence for humans (Homo sapiens), encoded as DNA within the 23 chromosome pairs in cell nuclei and in a small DNA molecule found within individual mitochondria.

Human skin color ranges in variety from the darkest brown to the lightest hues.

The genetic history of Europe is complicated because European populations have a complicated demographic history, including many successive periods of population growth.

2q37 monosomy is a rare genetic disorder caused by a deletion of a segment at the end of chromosome 2.

Research on heritability of IQ infers, from the similarity of IQ in closely related persons, the proportion of variance of IQ among individuals in a study population that is associated with genetic variation within that population.

Human genetic clustering is the degree to which human genetic variation can be partitioned into a small number of groups or clusters.

In human mitochondrial genetics, L is the mitochondrial DNA macro-haplogroup that is at the root of the human mtDNA phylogenetic tree.
