If changes in a genes' dna sequence can change proteins, which of the following statements is false?

a. phenotypes may be directly affected.
b. there is a molecular basis for genetic disorders.
c. amino acid sequences would be altered.
d. genetic disorders cannot be caused by changes in just one individual gene.

The false statement is  

D. Genetic disorders cannot be caused by changes in just one individual gene.

Explanation:

Genetic disorders are caused by changes in DNA sequence due to mutation which will result in protein alteration which causes different disorders

Not only in gene, a change in single nucleotide or deletion of single nucleotide in the DNA sequence can cause a genetic disorder.  

•there must be variation for the particular trait within a population.

•the variation must be inheritable (that is, it must be capable of being passed on from the parents to their offspring).

•individuals with one version of the trait must produce more offspring than those with a different version of the trait.good
