 New alleles are accumulating rapidly
in living populations and cellular mechanisms have not been adequately
sought to explain the intentional production of these changes. Homologous
DNA recombination occurs in all organisms and is at the heart of genetics.
Since its discovery during meiosis, these reactions were assumed to occur
randomly along the length of chromosomes, and only involved with gene
crossovers. It is now well known that meiotic recombination is not the
random process it was originally assumed to be, and controlled by highly
organized regulatory systems. In addition, a form of homologous
recombination has been discovered which is responsible for creating
diversity in variable genes, and was recently linked to single base-pair
substitutions in immunoglobulins. New allele formation may indeed be the key
to explaining the rapid production of distinct breeds, but their presence in
the genome has been assumed the result of random mutations. Therefore, the
ability of the cell to purposefully edit genes requires evaluation.

Thanks
again for speaking to DSA. I think the program went very well and
was tremendously interesting. You presented a technical talk in a
way that the main message came through to all present, even if they
were limited in genetics. Keith Swenson (DSA President).
