The lower melting point of the fat, evidently conferred by the 'A' gene - they may be homozygous (AA) or heterozygous (VA) - is part of the desirability of the Akaushi/Wagyu cattle, beyond just the high marbling trait. If I were crossbreeding with A or W, I would seek out sires that were AA genotype, in addition to scoring well for marbling and tepictures. Most semen distributors are supplying genomic test results for A/V status, as well as marbling/tenderness.
The photos I've seen of Akaushi bulls depict them to be 'beefier' animals than the typical black Wagyu bulls I've seen pictured.
Now you are making my head hurt.... Isn't Aa a genetic mutation from Av?
