polymorphic DNA

[SKA]

What is a polymorphic DNA locus?Does anyone know? Where can I find out?

[theprof]

As a professor of biochemistry, I know a reasonable amount about this subject.

The problem I have right now is that I have no idea how simple or complex a reply you require as you have not said why you want to know about it.

I have to be able to assess how much you know and understand already before I can even consider replying.

Not sure if that answers your question

[SKA]

To theprof Im doing a degree in Biological sciences and my lecturer just gave us some questions to do and that was one of them!

Hope your not my lecturer!! That would be weird!

Hi SKA

A polymorphic locus is a locus which may contain a number of possible alleles. An allele is a version of a particular gene which is responsible for a certain trait ( a good example is eye colour)

[theprof]

Yes, a polymorphic locus is a locus at which there are two or more alleles, each of which is present at a frequency of at least 1% in the animal population.

As you know, a locus in genetics means gene and alleles are different forms of the same gene. During gene mutation, many alleles appear and it is then termed a polymorphic locus. These alleles cause the variation in individuals in a species as dawkins explains.

Thanks alot everyone
