What percentage of plant DNA is the same as other plant DNA?

What percentage of plant DNA is the same as other plant DNA?

If it's possible can you also tell me, what percentage of one type of radish species is the same as another type of radish species?What percentage of plant DNA is the same as other plant DNA?

That totally depends on the species of plant you are comparing. Closely-related species (like two species of oak tree) will have more DNA in common than with a more distant plant (like a liverwort).

I'm not a botanist, I'm afraid - so I can't tell you difinitively.

I have been able to find a list of some radish species though:



- Raphanus sativus, the normal cultivated radish, which includes almost all commercially-grown varieties.

- R. raphanistrum (Wild Radish, or Jointedpodded Charlock). It was stated by Linnaeus that in wet seasons this abounds as a weed among barley, in Sweden, and being ground with the corn, it is eaten in barley bread, causing violent convulsive complaints, or an epidemic, spasmodic disease. Other authorities say that it is harmless, liked by domestic animals and bees. It is bristly, and has rather large, straw-coloured flowers.

- R. sibiricus, or Siberian Radish, has cylindrical pods.

- R. caudatus, the Java, or Rat's Tail Radish, a native of Final, furnishes long, edible pods, purple or violet in colour. They should be used half-grown. The root of this species is not used.

- R. maritimus is an indigenous, seaside variety.

- R. erucoides, of Italy, has pods with a beak of their own length, and a simple, biennial root, scarcely thicker than the stem.

- R. tenellus, another native of Siberia, flowers in Britain in June and July, having awl-shaped, jointed, two-celled, smooth pods.
