[QUOTE="MikeC, post: 156590, member: 1604"] I have read that because of "Mitochondrial DNA" the cow lends more genetic sequence to a calf than the bull. Up to 50% more. snip......... Mitochondrial DNA (mtDNA, or less popularly, mDNA) is DNA which is not located in the nucleus of the cell but in the mitochondria. Mitochondria are parts of the cell that generate fuel in the form of adenosine triphosphate (ATP), which drives the varied machinery of the cell. Unlike most of the cell, the function of which is defined by the nuclear DNA, the mitochondria have their own DNA and are assumed to have evolved separately. mtDNA is typically passed on only from the mother during sexual reproduction (mitochondrial genetics), meaning that the mitochondria are clones. This means that there is little change in the mtDNA from generation to generation, unlike nuclear DNA which changes by 50% each generation. Since the mutation rate is easily measured, mtDNA is a powerful tool for tracking matrilineage, and has been used in this role for tracking many species back thousands of generations. [/QUOTE]
