Unformatted text preview: recombination (unlinked genes) Recombination produces genotypes with new combinations of parental alleles. This can occur by interchromosomal recombination or independent assortment. Notice that the test cross produces the typical 1:1:1:1 ratio observed by Mendel BIS101001, Spring 2012--Genes and Gene Expression, R.L. Rodriguez 2012 9 March 19, 2012 Intrachromosomal recombination (linked genes) Recombination produces genotypes with new combinations of parental alleles. When genes are linked on the same chromosome, this can occur by intrachromosomal or meiotic recombinantion. Notice that the test cross does not produce the 1:1:1:1 ratio by something like, 0.8 : 0.8 : 0.2 : 0:2 March 19, 2012 BIS101001, Spring 2012--Genes and Gene Expression, R.L.
