BIOL3044 Lecture Notes - Lecture 29: Chromosome, Weighted Arithmetic Mean, Bc1
Document Summary
We have explored consequences of dominance for the fitness of hybrids: dominance tends to create high fitness in early generations of hybridization. Now we need to look at the effects of epistasis. Data comes from a study for qtl, studying genes for fertility in caenorhabditis. Here are averages of 4 possible homozygous genotypes of chromosome ii and iii: remember: chromosome iii has no qtl on it. If you take the average of all aa homozygotes on chromosome ii, it comes out to have a much higher average than the aa homozygotes. If you take the average of all bb homozygotes and bb homozygotes on chromosome iii, the averages are very similar to each other: shows there"s no significant affect on. Qtl: note the bb homozygotes for chromosome iii: average of bb paired with aa and. Bb paired with aa have very different averages: bb paired with aa and bb paired with aa on chromosome iii result in similar averages though.
