Natural selection is the process in which organisms with inheritable traits—genes— better suited to their environment tend to have more offspring than the other members of their population. These organisms therefore have a greater chance of passing on their genes to the next generation than the others. The favourable genes increase in frequency from generation to generation, while the less favourable ones virtually disappear. Through this process, the subsequent generations of that population will be more and more viable and adapted to their environment. It must be noted that the process of natural selection deletes genetic information (the weaker traits), it cannot create new information required by the evolutionary theory.

             Can anyone refer me to websites or books that talk about gaining genetic information through the evolutionary process?
Im confused about the topic.   I attended a ken ham creationists convention and he mentioned there is no gaining of genes through natural selection but only loss.   Is this true?

There is a bibliography of work on gene duplication here: Gene Duplication



One of the references is this paper which gives a nice detailed look. The Evolutionary Fate and Consequence of Duplicate Genes

Here is the data for you to look at in detail.
Gene Duplication Data from Science article




-------
Pogge:” This is the volume of a sphere with a 62 kilometer (about 39 miles) radius, which is considerably smaller than the 2,000 mile radius of the Earth.”
Wikipedia:” For Earth, the mean radius is 6,371.009 km(≈3,958.761 mi; ≈3,440.069 nmi).”
Wisp to Lester (on Pogge): Do you admit he was wrong about the basics?
Lester: No

Information can be gained.

Lets say you have a gene:

AAABBB (ten A, and ten B)

This entire gene can be duplicated:

AAABBBAAABBB

Now delete a bit:

AAABBBAAABBB (7xA, and 2xB)

Mutate a single B into an A

AAABBBAAABBBABBB

Duplicate the gene again:

AAABBBAAABBBABBBAAABBBAAABBBABBB

Delete a chunk:

AAABBBAAABBBABBBAAABBBAAAABBBABBB

I think you see where I am going. Obviously information can be added by mutations and other mistakes.

Yes it can through the duplication of genes and even entire chromosomes through
Polyploidy

These new sets of copies can undergo different mutations.
