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 If two pairs of identical twins, a male pair and female pair have children would the offspring look the same?
Answer Thanks for the question, Jodie. The offspring would look similar, but not identical. In fact, they would look about as similar as two siblings from the same couple. When a sperm and an ovum meet they exchange information in the form of chromosomes. The chromosomes exchanged will always be different, which is why sisters and brothers often have similar physical features, but are not identical (unless they are identical twins).
