Question

heterochromia is when a human or animal has two different eye colors. heterochromia can have many different causes. the cause of heterochromia determines its type and if it is heritable or not. the person in the image has heterochromia that occurred from a mutation during mitosis and is only found in the somatic cells of their body. which best describes why the person in the passage image has two eye colors? a mutation in a cell in one eye altered the dna to express a temporary change a mutation in a cell of one eye altered the dna to express a permanent change. a mutation in cells in both eyes altered the dna to express a permanent change a mutation in cells of both eyes altered the dna to express a temporary change

Explanation:

The passage states that the heterochromia occurred from a mutation during mitosis and is only in somatic cells. Somatic cell mutations are not passed on (so it's a non - hereditary, permanent change in the affected cells). Since only one eye is affected (heterochromia is two different eye colors), the mutation is in one eye. A mutation in DNA (especially in a somatic cell during mitosis) leads to a permanent change in the cell's characteristics (like eye color).

Answer:

B. A mutation in a cell of one eye altered the DNA to express a permanent change.
