Mouflon vignei" (or "orientalis") "arkal" and "O. v./o. bochariensis", grouped with two different clades of argali ("Ovis ammon"). The ancestral sheep is presumed to have had 60 chromosomes, as in goats ("Capra"). Mouflon and domestic sheep have 54 chromosomes, with three pairs (1+3, 2+8, 5+11) of ancestral acrocentric chromosomes joined to form bi-armed chromosomes. This is in contrast to the argali and urial, which have 56 and 58 chromosomes respectively. If the urial is as closely related to the mouflons as mitochondrial DNA indicates, then two chromosomes would need to have split during its evolution away from the mouflon (sub)species. In
Class A Wild Trout Waters Waters vary by species. For brook trout, a biomass of , including at least of brook trout less than long. Additionally, brook trout may not make up less than 75 percent of the total wild trout biomass. The requirements are the same for brown trout except that the minimum brown trout biomass is . For a stream to be Class A Wild Trout Waters for both brook trout and brown trout, the combined biomass of both species must be at least and the biomass of each species must include at least of trout less than long. Neither species may make
