Answer:
3. To identify dominant mutations, breed the
mutant individual to a wild-type individual.
Dominant mutations will be visible in the F1
4. The statement that correctly identifies how a
genetic mutation affects an organism is that
mutations can alter or stop the production
proteins in a way that either alters the
appearance or quality of life of an organism.
Explanation:
A genetic mutation occurs at the molecular
level, in the DNA, and consists of the change of
a specific sequence of nucleotides in the
nucleic acid.
Since the sequence of DNA bases determines
genetic information necessary for the synthesis
of specific proteins, changes in the sequence
can produce alterations in structural and
functional proteins -due to changes in the
sequence of amino acids or incomplete
synthesis- that affect the appearance or
functioning of a living being.
The other options are not correct because:
Although some mutations go unnoticed,
most can cause alterations in organisms.
Not all mutations are harmful or lead to
premature death.
Mutations do not produce new abilities.
