Question

A particular bird species found in North America obtains most of its food energy by catching and eating insects. A mutation arises in this bird population that increases the length of its beak. Although many mutations are harmful, this particular mutation has increased the ability of the bird to catch and eat certain insects. Formulate the MOST LIKELY outcome resulting from this mutation.

The insects that are eaten by this bird are likely to become extinct.
The insects that are eaten by this bird are likely to become extinct.

Sharp pointed beaks will result in the birds eating other more unusual food items.
Sharp pointed beaks will result in the birds eating other more unusual food items.

Other bird species will be more likely to also develop pointed beaks in order to compete.
Other bird species will be more likely to also develop pointed beaks in order to compete.

Individual birds with the mutation will be more likely to survive and reproduce than birds without the mutation.

Answer 1

For each genetic mutation described, classify its effects as harmful, beneficial, or neutral.


As biotechnology has improved, scientists are able to look more closely at DNA, the molecules that hold genetic instructions for development, reproduction, and functioning. The ability to study DNA closely allows scientists to find evidence of genetic mutation and better understand the effects of these changes. Think about how genetic mutations can be harmful, beneficial, or cause no change at all.

Beneficial Effect Neutral Effect Harmful Effect
A mutation occurs in a portion of DNA and does not change the amino acid sequence of a protein.
Beneficial Effect – A mutation occurs in a portion of DNA and does not change the amino acid sequence of a protein.
Neutral Effect – A mutation occurs in a portion of DNA and does not change the amino acid sequence of a protein.
Harmful Effect – A mutation occurs in a portion of DNA and does not change the amino acid sequence of a protein.
A mutation in the hemoglobin gene results in Sickle Cell Anemia.
Beneficial Effect – A mutation in the hemoglobin gene results in Sickle Cell Anemia.
Neutral Effect – A mutation in the hemoglobin gene results in Sickle Cell Anemia.
Harmful Effect – A mutation in the hemoglobin gene results in Sickle Cell Anemia.
A mutation of a protein results in protection against a destructive bacteria.
Beneficial Effect – A mutation of a protein results in protection against a destructive bacteria.
Neutral Effect – A mutation of a protein results in protection against a destructive bacteria.
Harmful Effect – A mutation of a protein results in protection against a destructive bacteria.

Answer 2

wrong

Answer 3

Individual birds with the mutation will be more likely to survive and reproduce than birds without the mutation.

Answer 4

Beneficial Effect - A mutation of a protein results in protection against a destructive bacteria.

Neutral Effect - A mutation of a protein results in protection against a destructive bacteria.

Harmful Effect - A mutation of a protein results in protection against a destructive bacteria.

Answer 5

I apologize for the mistake. Here is the correct classification:

A mutation occurs in a portion of DNA and does not change the amino acid sequence of a protein:
Neutral Effect - Because there is no change in the amino acid sequence of the protein, the mutation does not have a significant effect.

A mutation in the hemoglobin gene results in Sickle Cell Anemia:
Harmful Effect - Sickle Cell Anemia is a serious and debilitating condition caused by a mutation in the hemoglobin gene.

A mutation of a protein results in protection against a destructive bacteria:
Beneficial Effect - The mutation of the protein provides protection against a destructive bacteria, which is beneficial for the organism.
