Is There A Marbling Gene
The k232a polymorphism at the diacylglycerol o acyltransferase 1 dgat1 gene and the capn1 c 947 snp were associated with level of beef marbling.
Is there a marbling gene. 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 are so many selective breedling existing which have been emphasized for many years and carried out in large population for thousands of yeas. 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. However proving that could be tricky.
But they all carry the gene. It also looks like as a group the british breeds have a higher incidence for these genes. 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. There are substantial differences in marbling ability across breeds of cattle and within breeds of cattle.
Clem as far as i know there are two markers for marbling and three recognized genes for tenderness. 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. However the trait of marbling is difficult to improve by traditional selection because the heritability is low and measure for marbling is only possible after slaughter. By contrast with visual scores of marbling gave greater scatter did not demonstrate a sire effect and must be misleading in their present form.
Marbling is an important trait in characterization beef quality and a major factor for determining the price of beef in the korean beef market. The inheritance of marbling can be explained by this theory. In fact marbling is pretty common. You are bound to get at the least a quarter marbled fry.
Results of dataset 2 grouped by proportion of black wagyu are shown in figure 2. To find the candidate gene associated with marbling we used a weighted gene coexpression network analysis from the. 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.
In particular marbling is a complex trait and needs a system level approach for identifying candidate genes related to the trait. Heritability estimates of marbling ability have ranged from 13 to 88 in.
