Well, you would use Punnet squares. Don't forget that heterozygous means that the alleles are different so Rr. Homozygous means that the genotype will have the same genes rr. When you put together the Punnet squares, I always like to determine the percentage of phenotypes possible. In this case 50% of them are going to be white, and 50% of them are going to be red.

The given question is incomplete as the group of choices are missing, however, the group of choices are given as follows:

Select one

a. Protein consists partially of amine groups that are neutral as a result of protonation (of one H ion)

b.Protein contains deprotonated carboxylate groups, resulting in a negative charge

c. The carboxylate groups in protein act very much like carboxylic acid groups (-COOH), except that they are deprotonated

d. If the human body did not act like a buffer solution, each time you ingested an acid the carboxylate groups would protonate, causing the protein structure to disintegrate.

Answer:

The correct answer (incorrect statement) is : option C.

Explanation:

pH of blood should be remain 7.5 in order to make proteins of the body and blood intact and functional. Human protein have neutral amine group due to the protonation and negative carboxylate group due to the deprotonation.

carboxyl group behave like an acid and carboxylate group behave like a base due to the fact that Carboxylate group (-COO-) is conjugate base of Carboxyl group. Human body acts like buffer to prevent the protein from  disintegrate.

Thus, the correct answer is : option c.
