Dominant gene means that as long as one of the genes is dominant, it is dominant; Recessive gene means that both genes are expressed when they are invisible, otherwise they are dominant genes.
For example, a person's blood type is composed of A, B and I, A and B are dominant, I is invisible, you are AB, and your husband is ii(ii is type O blood). Your child will be arranged and combined by AB and ii (that is, you and your husband each have one gene), so your child's possible genes are: Ai (that is, blood type A), Bi (that is, blood type B), Bi.
Arrangement and combination mode
Pure hand tour, hope to adopt.
