A RH negative father has a RH negative son. What is the possibility of other children being RH negative? May we then conclude that the son's mother is also negative?
Everything relies upon the qualities conveyed by the mother. On the off chance that the mother is twofold passive, all kids end up negative; however, for this situation, child's mom may not be negative. Having a positive blood classification is controlled by the nearness of the RHD quality, which encodes for the Rh D Antigen on the surface of Red Blood Cells. On the off chance that that antigen is absent (because of imperfect qualities), at that point, the individual has a negative blood classification. The RDH quality is available in 2 duplicates in our qualities. In any case, only 1 duplicate is sufficient to have the Rh D Antigen and have a positive blood classification. Also, the other way around, you would need both 2 duplicates of the qualities to be deficient with the end goal to be negative blood composed.
