Answer:
Eye color is determined by variations in a person's genes. Most of the genes associated with eye color are involved in the production, transport, or storage of a pigment called melanin. Eye color is directly related to the amount and quality of melanin in the front layers of the iris.
The broad spectrum of colors can be attributed to multiple alleles. The correct option is B.
What is variation in human traits?
Variation is a word used for different traits present within the species, variation occurs due to recessive and dominant genes present in the organisms and due to mutation.
Mendel gave this theory that the alleles are given independently by the parents and one become recessive and one becomes dominant.
The difference in eye color is due to these alleles. Suppose the mother has black eyes and the father has blue eyes, the child can have both alleles, but only one will show. Mutation can also cause variation, maybe the child has totally different eyes than his parents.
Thus, the correct option is B. multiple alleles.
