A plant of genotype AB/ab- yes, the two genes are linked is testcrossed to an ab/ab plant. if the two genes are 10 map units apart, then what fraction of progeny will be AB/ab?
Homework Answers
The answer is 45% and the fraction is 45/100 or 4.5/10.

Disc 2, Bb# 3 In the morning glory plant, three genes are linked as follows: 20 m.u 30 m.u A morning glory plant with the genotype BB gg DD was crossed to a morning glory plant of genotype bb GG dd. The F1 progeny was testcrossed to a b g d/bg d plant. A. Assume no interference, what genotypic classes will be found in the progeny and the frequencies if there are 1000 progeny? B....

You are studying two linked, autosomal genes (A and B) in Drosophila. You make the following testcross between AB/ab (x) ab/abflies, and record the progeny results (see below). However, you have previously determined that the Aa/bb genotype is lethal in early embryogenesis (before hatching), and therefore these individuals never appear among the viable testcross progeny observed. Indicate the most accurate map distance between the A and B genes that can be determined from these data? Show all your work (scratch...

A purple flowering, smooth seed dihybrid plant (genotype PpSs)is test crossed with a white flowering, wrinkled seed plant(genotype ppss).These produce progeny inthe following numbers of four phenotypes:24:76:74:26 (purple flower + smooth seed coat: purple flower + wrinkled seed coat: white flower + smooth seed coat: white flower + wrinkled seed coat). a)Explain how ratios of progeny show that the two genes are linked. b)How many map units separate the colour and seed coat genes? Show your calculations.

genes A and B are 20 map units apart. If you cross Ab/aB xab/ab, how many each progeny type would you expect if total progeny was 1000. a. AaBb(AB/ab) b. Aabb ( Ab/ab) c. aaBb(aB/ab) d. aabb(ab/ab) is b and c the parental ? would that mean that b and c are 20 ? Thanks
