LDS Objections: Founder Effect
            
                  All
                    males descended from Lehi and all females descended from
                    Ishmael
                   
                   
                  Requires
                     mutations of at least:
                     
                    
                   
                  All
                     mutations must occur simultaneously and must
                    result in Asian haplotypes

How could founder effect and genetic drift account for the data from these
genetics studies? In the Book of Mormon, all the male founders of the Nephites
and Lamanites were descended from one man, Lehi. If Lehi harbored some kind of
skewed genetics, it would be reflected in his sons and their offspring. This
could explain some of the Y-chromosome data, which is passed on only through the
male line. However, since there are many different Y-chromosome haplotypes found
at many  loci, it is virtually impossible that  all of those  loci would be mutated
in any one individual. It gets much worse for the Mormon apologist. Lehi’s genetics
could not explain the  mtDNA genetics, since these  genes are passed on only
though the female line. The wives of Lehi’s sons were also from one family
line - Ishmael.  Since there are four main
Native American specific  mtDNA haplotypes, one would have to hypothesize that
all of these haplotypes were developed in the wives of Lehi’s sons or their
immediate daughters and that those haplotypes just happed to match those
of East Asians.
A third genetic technique examined the polymorphic Alu  insertions found in the
 autosomal (non-X or Y)  chromosomes. With results similar to the two other
genetic techniques, the founder effect would require the additional simultaneous  mutationof at least 5 polymorphic Alu  insertions in Lehi’s sons and son’s wives - not
likely! 
Not only do Mormon apologists have to deal with human genetics, they also
have to explain the genetics of certain intestinal bacteria and domesticated
dogs. In order for Native Americans to have been founded by Israelites, the Helicobacter pylori
in their gut would have had to mutate to match that of the Asian variety. In
addition, the dogs they took over to the Americas would have had to mutate to an
Asian type genetics. All of these five extremely improbable, multiple
 mutation effects would have had to have happened within one or two generations
in the same small populations. The idea is scientifically ludicrous.
