- The Y chromosome is one of two sex chromosomes ( allosomes) in therian mammals, including humans, and many other animals. The other is the X chromosome. Y is normally the sex-determining chromosome in many species, since it is the presence or absence of Y that determines the male or female sex of offspring produced in sexual reproduction.Centromere position: Acrocentric, (10.4 Mbp)Type: Allosome

In human genetics, a human Y-chromosome DNA haplogroup is a haplogroup defined by mutations in the non-recombining portions of DNA from the male-specific Y chromosome (called Y-DNA). Many people within a haplogroup share similar numbers of short tandem repeats (STRs) and types of mutations called single-nucleotide polymorphisms (SNPs).

The Y chromosome is a chromosome that decides the sex in most mammals, including humans. It contains the gene SRY, which triggers testis development, so making an animal male or female. Normal females have two X chromosomes, and normal males have one X and one Y. An egg always carries a single X, while sperms carry either an X or a Y.

- In human genetics, the Y-chromosomal most recent common ancestor is the patrilineal most recent common ancestor from whom all currently living humans are descended. He is the most recent male from whom all living humans are descended through an unbroken line of their male ancestors. The term Y-MRCA reflects the fact that the Y chromosomes of all cu...

Y-chromosomal Aaron is the name given to the hypothesized most recent common ancestor of the patrilineal Jewish priestly caste known as Kohanim. According to the traditional understanding of the Hebrew Bible, this ancestor was Aaron, the brother of Moses. While some early genetic studies were seen as possibly supporting the traditional biblical narrative, this …

The SNP that defines the T1 clade is L206. The haplogroup is one of two primary branches of T (T-M184), the other subclade being T2 (T-PH110).

The condition is generally not inherited …
