Chapter 7, Problem 15E
Which Of the following statements about graded potentials is false?
- The magnitude of a graded potential varies with the strength of the stimulus.
- Some graded potentials are hyperpolarizations; others are depolarizations.
- Graded potentials are produced at ligand-gated ion channels.
- Graded potentials can sum over space and time.
- Graded potentials are limited in duration by the refractory period.

Three of the many recessive mutations in Drosophila melanogaster that affect body color, wing shape, or bristle morphology are black (b) body versus grey in wild type, dumpy (dp), obliquely truncated wings versus long wings in the male, and hooked (hk) bristles versus not hooked in the wild type. From a cross of a dumpy female with a black and hooked male, all of the F1 were wild type for all three of the characters. The testcross of an F1 female with a dumpy, black, hooked male gave the following results:

Determine the order of the genes and the mapping distance between genes.
Determine the coefficient of confidence for the portion of the chromosome involved in the cross. How much interference takes place in the cross?
What happens to a microbes membrane at colder temperature?
Genes at loci f, m, and w are linked, but their order is unknown. The F1 heterozygotes from a cross of FFMMWW x ffmmww are test crossed. The most frequent phenotypes in the test cross progeny will be FMW and fmw regardless of what the gene order turns out to be.
What classes of testcross progeny (phenotypes) would be least frequent if locus m is in the middle?
What classes would be least frequent if locus f is in the middle?
What classes would be least frequent if locus w is in the middle?
