Refer to this experiment in fruit flies, rough eyes (ro), ebony body (eb), and scarlet eyes (st) are recessive to wild-type alleles (rot, eb+ and st+). These three genes are linked and on chromosome 3. An individual that is homozygous for all three traits is mated with an individual that is homozygous for the wild-type (dominant) traits. F1 females are crossed with males homozygous for all three traits (tester). The genotypes and numbers of the offspring are listed in the table below. Genotype Numbers ro+ eb+st+/ro eb st 1195 ro eb+st+/ro eb st 701 ro+eb st/ro eb st 699 ro+ eb+ st/ro eb st 233 ro eb+ st/ro eb st 20 ro+ eb st+/ro eb st 25 ro eb st+/ro eb st 227 roeb st/ro eb st 1205 What is the recombination frequency between the two eye traits?
