How to do genetic ratios
WebYou can use this information to construct expected ratios for two or more loci. Example 1: Consider the following cross: A homozygous gray, bicorn dust rhino is crossed to a homozygous white, unicorn dust rhino. The F 1 are all gray, bicorn. The F 1 progeny are intercrossed to get an F 2.What are the expected progeny ratios in the F 2?. As … WebTo show how inheritance works we can use genetic diagrams and punnet squares.
