Answer:
The correct answer is "pepsin".
Explanation:
Pepsin is an enzyme that catalyzes the hydrolysis of proteins, breaking it down into its subunits called amino acids. Pepsin is an important component of the gastric juice because it contributes largely to proteins digestion. In this case, James is having trouble to digest lean steaks and other protein-rich foods. This problem indicates that James is likely lacking the enzyme pepsin.
100% will have that allele. Homozygous means the alleles are the same for every gamete, for example looking at Mendel's pea plants, if the allele for the trait of growing tall is T and the allele for growing short is t, a homozygous tall pea plant would have the genotype TT, meaning all of its alleles are tall
