Answer:
Because the probability of hemophilia would be 1:4
Explanation:
Hemophilia is a disease that comes with a sex chromosome (pair 46).
It is a recessive allele associated with chromosome X, women have two X chromosomes they can carry it, but they don't have it because they have another dominand allele non-hemophilic.
If you draw a Punnet square with a non-hemophilic father and a carrying mother, you'll found you have 1:4 chances of having a baby boy with hemophilia.
Carrying mother = X(H)X(h)
Father = X(H) Y

Answer:
The correct answer is a gene
Explanation:
The DNA segment that carries information for coding one protein or polypeptide is called a gene. According to one gene-one polypeptide hypothesis, each gene is responsible for making a single chain of the polypeptide.
Originally it was said that one gene codes for one enzyme but later it was found that some gene also codes for non-enzyme proteins and single polypeptide chains. So after this research, the theory was modified and one gene-one polypeptide theory came. Therefore the right answer is gene.
