![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
