For the following crosses, you will need to recall that ldeno by cross-fertilization between a male and a hermaphrodite or by self-fertilization of the hermaphrodite. In addition, males are chromosomally XO (that is, a single X chromosome and no other chromosome), while hermaphrodites are XX. elegans can reproduce A wild-type male mates with a hermaphrodite that is both unusually long (lon) and has uncoordinated (unc) movement. All of the F, male offspring are long but with normal movement, while all of the F, hermaphrodite offspring are normal in both body length and movement. a. What can you determine about the linkage or chromosomal locations of the lon and the unc genes? b.

If the F, hermaphrodites are instead allowed to self-fertilize, what phenotypes are expected in the F, generation, and in what proportions?

8.16 For the following crosses, you will need to recall that Caenorhabditis elegans can reproduce by cross-fertilization between a male and a hermaphrodite or by self-fertilization of the hermaphrodite. In addition, males are chromosomally XO (that is, a single X chromosome and no other chromosome), while hermaphrodites are XX. A wild-type male mates with a hermaphrodite that is both unusually long (lon) and has uncoordinated (unc) movement. All of the F, male offspring are long but with normal movement, while all of the F, hermaphrodite offspring are normal in both body length and movement. a. What can you determine about the linkage or chromosomal locations of the lon and the unc genes? b. If the lon F, males are mated to the F, hermaphrodites, what phenotypes are expected among the cross-progeny in the F, generation, and in what proportions? c.
