Question details

utlthnu ie plaled out on plates containing rifampicin, 35 colonies are counted. What is the probability of obtaining a colony resistant to both streptomycin and rifampicin? The nematode Caenorhabditis elegans can reproduce by self-fertilization or cross- fertilization. Hermaphrodites are capable of self-fertilization or cross-fertilization by mating with a male. A wild-type male with normal movement is mated to a paralyzed hermaphrodite. All of the F, offspring are capable of movement.One of the F, offspring is allowed to self-fertilize to produce an F, generation. a. Which allele is dominant,and which is recessive? b. Among the F, generation worms, what fraction of them do you predict will be paralyzed? c. When an observant student did the cross, she noticed that some of the worms in the d,en the samè number of 9 5.18 ahead F2 generation moved normally, some were paralyzed, and some moved sluggishly although they could move. She decided to count the number of worms in each category, with the following results. Normal movement 73 Paralyzed 66 Sluggish but moving 139
How might you explain these results? What do these results suggest about the F worms that are sluggish but capable of movement? d. Test your hypothesis about the results in (c) by using a x2 test.Please help
