The human genome is a complete set of nucleic acid sequences for humans, encoded as the DNA within each of the 24 distinct chromosomes in the cell nucleus. A small DNA molecule is found within individual mitochondria. These are usually treated separately as the nuclear genome and the mitochondrial genome. [1]
After telling of the baptism of Jesus, Luke 3:23–38 states, "Jesus himself began to be about thirty years of age, being (as was supposed) the son of Joseph, which was [the son] of Heli, ..." (3:23) and continues on until "Adam, which was [the son] of God." (3:38) The Greek text of Luke's Gospel does not use the word "son" in the genealogy ...
Schematic karyogram showing the human genome, with 23 chromosome pairs, and the human mitochondrial genome to scale at bottom left (annotated "MT").Its genome is relatively tiny compared to the rest, and its copy number per human cell varies from 0 (erythrocytes) [1] up to 1,500,000 ().

This occurs when certain types of germ cells undergo meiosis to split the normal diploid number of chromosomes (n=46) into haploid cells containing only 23 chromosomes. [10] Anatomy of the testis. In males, this process is known as spermatogenesis and occurs only after puberty in the seminiferous tubules of the testes.
Females therefore have 23 homologous chromosome pairs, while males have 22. The X and Y chromosomes have small regions of homology called pseudoautosomal regions. An X chromosome is always present as the 23rd chromosome in the ovum, while either an X or Y chromosome may be present in an individual sperm. [4]
DNA from human remains found in a medieval well suggests they belonged to Ashkenazi Jews who fell victim to antisemitic violence during the 12th century.
