Merle is a pattern dilution gene. This means that the dogs original coat colour is diluted by the Merle gene in a pattern unique to every dog. For example, Blue Merle is the result of the Merle gene over a black coat while Red Merle is the result of the Merle gene over a chocolate coat. The Merle gene is not physically displayed in coat colours that are too pale for the Merle gene to dilute, this includes; red/tan, gold, cream, sable and fawn.
White cloudy urine in men may be caused by the presence of semen in the urine. This milky colored urine in males commonly occurs after an ejaculation. Cloudy urine may also occur after drinking alcohol. A darkish appearance to the urine may signify a problem with the liver such as cirrhosis or acute viral hepatitis.
Normal urine is clear and has a straw-yellow color. When the urine does not have its characteristic clear appearance, it is often referred to as cloudy, turbid, or foamy urine. Cloudy or foamy urine may occur occasionally due to mild dehydration; when it occurs in the absence of symptoms and goes away rapidly, it is usually of little consequence. Certain conditions can cause excess protein or crystalline substances in the urine, causing it to persistently appear cloudy or foamy. Infections anywhere in the urinary tract can cause blood and pus to appear in the urine, giving it a cloudy appearance. Additionally, many of the numerous causes of blood in the urine can yield a cloudy or murky appearance to the urine due to the presence of blood.
