2 Nov 2009, 3:07 PM | Re: LINKED GENES help! The inheritance of linked genes leads to the simple Mendelian ratio 3:1 because the alleles are on the same chromatid and the whole chromatid moves completely to the new cell. Only if crossing-over occurs will this ratio change, which is the case for dihybrid crosses giving the 9:3:3:1 ratio. I personally hate linked genes lol im not sure how to explain it using punnet squares though |
