Zebrafish genetics

Zebrafish have about 300,000 antibody-producing B cells

Bovine genetics

The bovine genome has properbly over 22,000 genes

Greatest genetic diversity is in indicine Brahmin cattle with one SNP(DNA sequence variant) every 285 base pairs of DNA.


Humped and humpless cattle diverged about 250,000 years ago

Brain genes

Aspm,cdk5rap2,cenpj and mcph1 are involved in controlling brain size and mutations in these genes can scause microcephaly.

I have started a new blog called http://scientifictoolsandequiment.blogspot.com/ which descrides tools etc which are used to do genetic analyses.

Ear and hearing genes

The protein nAChR, located on sensory hair cells in the inner ear kicks in when sounds register as too loud, liniting the ability of hair cells to respond.

Genes linked to gut, stomach and bowel.

The MET gene plays a role in repairing damaged gut tissue.(same gene appears to be implicated in autism)
