In mice, the waltzing allele (w) that causes the mouse to run in circles due to an inner ear defect is recessive to the non-waltzing allele (W). In an ideal mouse population exhibiting Hardy–Weinberg equilibrium of 150 mice, 15% of the alleles are non-waltzing. What is the frequency of the recessive allele? Record your answer as a whole number percentage.

Phenylthiocarbamide (PTC) is an organic compound that either tastes extremely bitter or is tasteless, depending on the genotype of the taster. The tasting allele is dominant over the non-tasting allele. Normal skin pigmentation is dominant over albinism. (It is important to note that this example of PTC tasting cannot be explained with simple genetics, but for the purpose of this question, assume that it can.) A normally-pigmented woman who cannot taste PTC has an albino father who can taste PTC. The woman married an albino man who can taste PTC and whose mother cannot taste PTC. For the married couple,

If so how can I tell whether it is or not?
