What are the chances of two individuals having a child with tay-sachs if the father is an ashkenazi carrier and the mother is a french-canadian carrier?

Respuesta :

The formula that we will be using to solve this problem is:[Likelihood of mom being a carrier] × [Likelihood of dad being a carrier] × [Likelihood of having an affected child if both parents are carriers]So plugging in the values:(1/30) × (1/300) × ¼ = 2.77 × 10 ^ -5
