Nearsightedness is dominant to normal vision and hazel eyes are dominant to blue eyes. A nearsighted woman with hazel eyes who is heterozygous for both traitsmarries a man with normal vision and hazel eyes. His genotype for eye color is the same as his wife's. Their three children all have blue eyes and normal vision. What is the probability that their next child will have blue eyes and be nearsighted

Sagot :

In this case we will deal with genetics and use the genes to know the probability of the child being born with blue eyes, in this case it will be 1/4.

What is genetic probability?

Probability serves to mathematically estimate the possibility of events that happen by chance, that is, as a matter of luck. It can be defined by the following formula:

  • P is the probability that an event will occur
  • A is the number of desired events
  • S is the total number of possible events.

In this case,

  • the gemetes from the mother will be NH, Nh, nH and nh
  • the gametes from the father will be nH and nh

Based on the parent genotypes a child with nearsight and blue eyes will have the genotype Nnhh. This will be:

1/2 x 1/2 = 1/4
