Dominant: Positive is dominant over negative. You get one gene from each of your parents, so you are either --, -+, +-, or ++. Only in the case of -- will you have rh negative blood. With -+, +-, and ++, you will have rh positive blood. This makes rh positive blood the most common type of the two.

If either parent had two copies of the gene an o type would be impossible. ...Read more
Yes, not Right Issue: Blood type: thousands of proteins on the surface of cells. Abo & rh were the first 2 & most important (in terms of transfusion reactions) types characterized historically. There are hundreds more "types". O means neither a or b. A means a from 1 parent. B means b from 1 parent. Thus a+a, b+b, a+b or o. Rh+ means present. Rh- means not present. A o+rh- mom might reject a+b+rh+ fetus but usually ok. ...Read more
