[rottndog:] Tomato and human DNA is 50% identical.

No it isn't, but thanks for playing.

[rottndog:] WHOOOPEEEDOOOO!!!!

Thank you for your, um, enlightening contribution to a complex and technical topic.

[ikka:] Oranges and human beings share 75% of DNA .

Wrong again.

Are you guys cribbing from the same creationist propaganda, or what?

The human genome is 3.50 picograms in size (a picogram is a measure of weight, equivalent to roughly a billion basepairs).

The tomato genome is 1.01 picograms in size (average across several species of tomato).

The orange genome is 0.44 picograms in size (average across several species of citrus).

Given the size differences in the genomes, the absolute maximum possible amount of match between the DNA of humans and tomatoes would be 1.01/3.50 = 28.9%, and that high-end figure would be reached only if *EVERY* single basepair sequence in the 1.01pg tomato genome had a ONE HUNDRED PERCENT IDENTICAL MATCH in the human genome (leaving the other, additional 2.49pg of the human genome unmatchable). And needless to say, that "best case" match isn't actually true. The actual degree of match is far, far less than that.

Similarly, the maximum possible match between the DNA sequences of humans and oranges would be 12.6%.

Whoever told you that somehow human DNA is "50% identical" to that of a tomato, or that human and oranges "share 75% of DNA", either didn't know what in the heck they were talking about, or were being dishonest.

The actual gram amount of DNA has nothing to do with anything relating to base pair similarities between species, or with any sort of strutcural functional considerations.

You win the prize for most off the wall meaningless comment that demonstrates absolute ignorance on a subject.

Prior to this I actually thought you knew what DNA was.
