2. ### Bio- The ability to taste phenylthiocarbamide ( PTC ) is controlled in humans by a single dominant allele (T).?

Hey, A pedigree is a type of diagram, so i cant answer this online. but i can help with the theoretical part. you make Taster = T and Non- Taster = t therefore, the woman genotype was = tt the man is = T (and either T or t) But...

4. ### The ability to taste the chemical PTC is determined by a single gene in humans with the ability to taste given?

If you made a punnet square then you would get the following genotypes: TT, Tt, Tt, tt So 3/4 of their children should be tasters (TT, Tt) and 1/4 of their children should be...

5. ### If one parent is a homozygous for PTC tasting, could some of the children be non - tasters?

The homozygous dominant taster TT will pass on a dominant T allele to all children, so they will all be tasters.

6. ### The allele for PTC tasting is inherited as a dominant. Use T for tasters and t for nontasters and answer the f?

a. TT and Tt are tasters b. tt is unable to taste c. hmm...100-60=40, it would be more interesting to use Hardy-Wienberg to determine the frequency of tasters vs. non-tasters. p=freq T, q= freq t p^2= freq Tt, 2pq...

10. ### Would the frequencies of the alleles for PTC tasting and non-tasting remain constant over time? Why or why not?

They should, because reproduction is random with respect to taster/nontaster phenotype. That is, people who are tasters are not more likely to have more children than nontasters.
