 Human :: Mammal : Gourt
Humans, or human beings, are bipedal primates belonging to the mammalian species Homo sapiens (Latin for "wise man" or "knowing man") under the family Hominidae (the great apes).
Humans create complex social structures composed of co-operating and competing groups, ranging in scale from nations to individual families, and social interaction between humans has established a variety of traditions, rituals, ethics, values, social norms, and laws which form the basis of human society.
Humans are also noted for their desire to understand and influence the world around them, seeking to explain and manipulate natural phenomena through science, religion, philosophy and mythology.

Having identified QTL (Quantitative Trait Loci) for fatness on chicken chromosome 5 [12], our objective was to build a high-resolution and gene-rich RH map for this chromosome, as a basis for high precision comparative mapping with human and for the development of new polymorphic markers.
This result can have two origins: first, the kb/cR ratio is not constant from one chromosome to another, regardless of their physical length [18,19,14]; second, the previous calculations were based on physical length values estimated from cytogenetic studies: 21 Mb for GGA15 [20] and 41 Mb for GGA7 [21].
As indicated earlier [13,22-28], conserved synteny was observed between this chicken chromosome and portions of human chromosomes 11, 14 and 15.

 Imprinted gene found on human chromosome 19
For imprinted genes, the gene copy that is turned on depends only on whether it came from the mother or father, rather than on the classic laws of Mendelian genetics, where genes are either dominant or recessive.
Imprinted genes usually occur in clusters, so the researchers are now looking for other imprinted genes in the region of chromosome 19 near PEG3, said Duke's Susan Murphy, lead author of the study, which was funded by the National Institutes of Health.
In addition to being the first evidence of imprinting on chromosome 19, the PEG3 findings indicate the possibility that the similarities between the human and mouse versions of the gene might extend to behavior changes caused by loss of the gene's function in mice, the researchers said.
