please draw map for points!!!!*******orkuanswer for Th Drosophila, brittle (b). ebony body (e) and gaucho (g) are three recessive genes If homozygous EBONY females are crossed with homozygous BRITTLE&GAUCHO; males, the resulting F1 progeny are all wild-type If heterozygous F1 females are mated with EBONY BRITTLE & GAUCHO males, the following 1,000 progeny appear brittle, gaucho: 290 a) Derive a map for the three C Derive a map for the three genes ebony: 280 brittle, ebony: 8 gaucho: 12 brittle: 120 ebony, gaucho: 110 wild-type: 88 rittle, gaucho, ebony: 92
Explanation / Answer
brittle:bb, ebony:ee, guacho:gg
bEG (female) * Beg (male)= F1 BbEeGg wild type gamets bE,bG,EG
BBeeGG (ebony) = 280 brittle guacho (bbEEgg) = 290
brittle (bbEEGG) =120 brittle ebony (bbeeGG) =8
guacho (BBEEgg)=12 ebony guacho (BBeegg) =110
wild (BBEEGG)=88 brittle ebony guacho (bbeegg)=92
BBeeGG, bbEEgg = parental genotype double cross over =BBEEgg and bbeeGG
sequence of the genes on the map = BB, GG, EE
map position of between B and E= 1.04cM, B and G= 0.128, E and G= 0.28cM
