what part and how much of the dna comes from the human father?

50% (half of the chromosomes). of the nuclear DNA, 0% of the mitochondrial one.CyrilleDunant 18:38, 25 September 2005 (UTC)[reply]

Aah, only roughly. If you are male and you have an XY sex determination system, like humans do, you receive slightly less than 50% from your father since the Y chromosome you receive is shorter than the X you would have if you were a girl. Dunc|☺ 19:02, 25 September 2005 (UTC)[reply]

Mammals and vertebrates[edit]

The phrase "mammals and vertebrates" is a pointless since all mammals are vertebrates. Rob Burbidge (talk) 06:48, 3 July 2012 (UTC)[reply]

The first three sentences in the article confuse me. The first two sentence make a distinction between nuclear DNA (nDNA) and mitochondrial DNA (mtDNA) But then the third sentence reads: "Of the 23 pairs of chromosomes in the human body, 22 are of nuclear DNA." And this suggests that the remaining pair is mitochondrial DNA. But this sentence is no longer talking about the difference between nDNA and mtDNA. It is talking about nuclear DNA and distinguishing between the 22 pairs of autosomes and the single allosome pair, which is also known as the sex chromosomes. But aren't both autosomes and allosomes nuclear DNA? If the sex chromosomes are not nDNA and are not mtDNA, then what are they? Alpickrel (talk) 19:19, 27 July 2013 (UTC)[reply]

The article was wrong, as was the link being used to source that statement. All 23 pairs of chromosomes are located in the nucleus, even the smallest of those chromosome is around 48 million base pairs where as the mitochondrial DNA is around 16,000 bps.AioftheStorm (talk) 07:04, 18 January 2014 (UTC)[reply]
