An individual who is heterozygous for hair colour would have

Question

Quizplus · Accepted Answer

Heterozygous means having two different alleles for a particular gene. In the case of hair colour, this means having one allele for dark hair and one for blond hair, which can result in a mix of the two colours or a shade that is somewhere in between. Option A is incorrect because it refers to alleles for eye colour, not hair colour. Option C is not correct as there are no known alleles for eye colour that can result in blond eyes. Option D is also incorrect because it assumes that the heterozygous individual must have blond hair, which is not necessarily true.
