The recessive mutations cinnebar (cn - bright red eyes), curved (c - wings curve up) and plexus (px - extra wing veins) are all located on the 2nd chromosome of Drosophila. From a cross of cn c px/+++ females and cn c px males progeny with the following phenotypes are obtained: cn c px 296 + + + 329 cn c + 63 + + px 82 cn + + 119 + c px 86 cn + px 10 + c + 15 What is the gene order? and What is the frequency of recombination between cn and c?
