Question

Sharon has green eyes. Her mother has brown eyes, and her dad has blue eyes. Which two statements best explain eye color in Sharon’s family

Answer 1

her mother's eyes in good because it is in Brown colour. Sharon has green colour and her dad has blue colour eyes

Answer 2

Eye colour of human is determined by various genes. But most simply it can be demonstrated by solving it by Punnett square.

As her mother has brown eyes, the possibility of her gene distribution is 2-

i) BB & ii) Bb

With two dominant alleles in one case and in another a recessive allele with a dominant one.

But her dad can possibly have only one gene distribution - bb (as blue eyes are a recessive trait).

Check out the attached image.

There is O% possibility to have a green eye coloured kid when parents are blue and brown eye coloured.

Thus either Sharon is adopted or she has some paternal dispute.
