Question

a.Suppose that the ability to synthesize a hair follicle is dominant over the inability to generate a hair follicle. What letter symbol would you use to represent the allele that can generate a hair follicle? What letter symbol would you use to represent the allele that cannot generate a hair follicle?

(b) Suppose that the ability to synthesize the pore-blocking proteins is dominant over the inability to synthesize the pore blocking proteins. What letter symbol would you use to represent the allele that can synthesize the pore-blocking proteins? What letter symbol would you use to represent the allele that cannot synthesize the pore-blocking proteins?

(c) Using the letter symbols you chose in parts a and b, list all the possible genotypes that would result in a hobbit having hairy toes.

(d) Using the letter symbols you chose in parts a and b, list all the possible genotypes that would result in a hobbit having no hair on his toes.

(e) Is it possible for a hobbit to be homozygous for the ability to synthesize hair follicles, but yet have hairless toes? Explain your answer.

Explanation / Answer

a. Letter use t generate hair follicle: F

Letter use not to generate hair follicle: f

b. Synthesise block protein: P

    Cannot sysnthesise block protein: p

c. Genotypes having hairy toe: FFPP, FFPp, FfPP, FfPp

d. Genotypes having no hair toes: ffpp

e. It is possible to synthesise hair follicles by means of gene therapy
