AboutSophia Jane Expertise I can answer basic questions related to heritable diseases, and moderate level questions regarding genetics and biology in general. Please, no questions on what your future children will look like. I will happily answer questions regarding the inheritance of hair or eye colour, genetic diseases, genetic traits, etc..., but anything phrased as "I look like X and my partner look like Y; what will our baby look like?" will be sent to the question pool.

Question My wife is A+ & I am O+. What blood type will our baby be and how is this
determined? Can you explain it step by step? Thank you!
Answer Thanks for the question, Carl. Blood type is determined by the blood group (A, B, AB, or O) and the rhesus factor (+ or -). A person with an A blood group can either have an AA or AO genotype. The O blood group is recessive, and a person with the O blood group will have the OO genotype.
Based on the blood type of you and your partner, your child will either be A+ or O+.
