The Navajo Indians are the largest federally recognized Native American Indian tribe in the United States.

The Navajo use the name Dine because it refers to a term from the Navajo language that means people.
Males with Klinefelter's syndrome have two X chromosomes (47,XXY), in rare cases three (48,XXXY) or four (49,XXXXY) X-chromosomes. The X-chromosomes carry genes in terms of development of testicles, sex hormone production and physical sex development in general as well as to a certain extent also height growth.
Klinefelter syndrome is a group of conditions that affects the health of males who are born with at least one extra X chromosome. Chromosomes, found in all body cells, contain genes. Genes provide specific instructions for body characteristics and functions. For example, some genes determine height and hair color.
