Answer:
Some positive ressecive traits that humans have are (just to name a few), Able to bend your body (flexibility), Dimples, Long eyelashes, Freckles, Hair color, Thin lips, negative Rh factor in the blood, Tongue rolling (side edges up).
Really these are just a few that I mentioned. Except for the negative Rh factor, this can affect pregnancy. If your blood cells have this protein, you are Rh-positive. If your blood cells do not have this protein, you are Rh-negative. During pregnancy, problems can occur if you are Rh-negative and your fetus is Rh-positive. But people with Rh-negative do have some advantages. Rh-negative people may be immune to other parasites or viruses, some of which may not have been discovered yet.
