Polymorphism and Mutation

... of genes that have changed enough to create variation within a group. It is these changes that can lead to evolutionary changes since if this polymorphic change is beneficial it will continue to spread within the group as new offspring are produced. I suppose a mutation may become a polymorphism ...

How to draw a blot from a RFLP physical map?

... with the numbers at the bottom( the numbers are beneath the vertical lines ) represent restriction sites for the enzyme EcoRI.; Sites 3 and 4 are polymorphic; the others are not. The distances between EcoRI sites are given. The extent of the probe you are using to detect the RFLP is indicated ...

Re: Evolutionists Show of Shutting Down the Debate

... difference between a state where a gene has more than one form, and the various forms themselves. I agree that loci can be referred to as being polymorphic if they contain polymorphisms - ie. the loci possess "many forms". The word "polymorphism", unfortunately for our discussion, ...

Re: Analyzing gel electrophoresis picture?!

it looks like a picture representing RFLP analysis of a 250bp-long DNA fragment on which one polymorphic restriction cut site is located (at around 175th bp). these three samples should have been collected from three different individuals. lane2 and lane3 represents the ...
