In particular marbling is a complex trait and needs a system level approach for identifying candidate genes related to the trait. To find the candidate gene associated with marbling we used a weighted gene coexpression network analysis from the. 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.

You are bound to get at the least a quarter marbled fry.

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. 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. Now let s say you breed 2 marbled betta. 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.
