Sequencing

sorry let me rephrase my question how exactly is the assembly done ? I am asking this because how specifically do they detect heterozygosity ?

Re: How to read tricky electropherograms?

... signals. Background noise, however, is common. If your sequence is generally clean and you come across sites as in your examples, I would suspect heterozygosity at both sites. Ideally, it is best to have known homozygotes as controls for interpreting such data.

Re: Genetic diversity on squirrels

... that just be (total # of alleles)/11 calculated for each column? The allele frequencies should just be read off the table, I think. Then the %heterozygosity for each locus can be calculated per taxon with Hardy-Weinberg, as above, and the average heterozygosity would be the average of the ...

Re: Genetic diversity on squirrels

I’m not at all sure I’m doing this correctly—I’m not a geneticist by trade. It seems to me that the average heterozygosity is zero for douglasii (100% homozygous for TfC) and S. parryii (100% homozygous for TfA)—unless you have to take into account the possibilty of a sampling ...
