Why are peaches and nectarines so similar?
« on: 27/05/2009 21:07:49 »
I was eating a particularly lovely peach this afternoon, but it got me thinking about nectarines. As far as I can tell, the only difference between them is their skin; furry vs smooth. Why is this? Did they diverge on their evolutionary paths? I can't think of circumstances that would favour a furry skin in one location or a smooth skin in another. Perhaps it was a genetic 'mistake' in a geographically isolated population?

Any ideas?

Just one:

The nectarine is a cultivar group of peach that has a smooth, fuzzless skin. Though fuzzy peaches and nectarines are commercially regarded as different fruits, with nectarines often erroneously believed to be a crossbreed between peaches and plums, or a "peach with a plum skin", they belong to the same species as peaches. Several genetic studies have concluded in fact that nectarines are created due to a recessive gene, whereas a fuzzy peach skin is dominant. Nectarines have arisen many times from peach trees, often as bud sports.
