Is there a marbling gene.

Now let s say you breed 2 marbled betta. Like all things genetic however using a 10 star bull won t necessarily produce high marbling tender offspring. But they all carry the gene. Epds estimate the genetic potential of an animal as a parent across all gene loci involved whereas genetic tests are specific to a small number of genes or genetic.

It is a partially recessive genetic so if you have a betta with the marbling gene and you breed it to a betta with no marbling genetics you might get a few marbled fry. The k232a polymorphism at the diacylglycerol o acyltransferase 1 dgat1 gene and the capn1 c 947 snp were associated with level of beef marbling. In wagyu falls with days on feed and proportion of wagyu notwithstanding the genetic effects there is also a major environmental effect on and marbling. There is a need to identify functional modules or genes related to marbling traits and investigate their relationships through a weighted gene co expression network analysis based on the system level.

There was no association between the snp at the calpastatin gene cast c 155 and meat quality traits nor was there any association of the tested snps with whc traits and ph value. Clem as far as i know there are two markers for marbling and three recognized genes for tenderness. Marbling is an important trait in characterization beef quality and a major factor for determining the price of beef in the korean beef market. In particular marbling is a complex trait and needs a system level approach for identifying candidate genes related to the trait.

It also looks like as a group the british breeds have a higher incidence for these genes. Until now there was no comprehensive review of research into the genetics of marbling but texas a m geneticist andy herring recently completed the white paper genetic aspects of marbling in beef carcasses the literature review encompasses 52 studies spanning several decades. There are so many selective breedling existing which have been emphasized for many years and carried out in large population for thousands of yeas. Results of dataset 2 grouped by proportion of black wagyu are shown in figure 2.

There are substantial differences in marbling ability across breeds of cattle and within breeds of cattle. In fact marbling is pretty common. There is a lot of evidence to suggest that transposable genetic elements or jumping genes could be responsible for the marbling effect in betta fish. Heritability estimates of marbling ability have ranged from 13 to 88 in.

To find the candidate gene associated with marbling we used a weighted gene coexpression network analysis from the. However proving that could be tricky.
