Most Americans are Rh positive.
According to my book, PhysioEX 8.0 for Human Physiology, Americans are 85% Rh positive.
Are most Americans Rh positive or Rh Negative
The percentage varies according to race. About 85% of Americans have Rh+ blood. In China, the percentage is over 99%. The worldwide percentage is about 90%.
O Rh D Positive is not any thing . there is no Rh so there is no O Rh Positive.
If a person has the Rh factor, then they are positive. If they don't have the Rh factor, they are negative. The Rh factor is dominant, so a mother with it would have an Rh positive baby even if the father is negative for the Rh factor.
Rh positive is more common than Rh negative. Approximately 85% of the population is Rh positive.
It depends on the genotype of the Rh+ parent. If that person is heterozygous, then yes there is a 50% chance of an Rh- baby.Father's Group (negative)Mother's Group (positive heterozygous)Rh +Rh -Rh -Rh +, Rh -Rh -, Rh -Rh -Rh +, Rh -Rh - Rh -http://www.bloodbook.com/inherited.htmlIf the positive parent is homozygous, the baby will be positive:Father's Group (negative)Mother's Group (positive homozygous)Rh +Rh +Rh -Rh +, Rh -Rh +, Rh -Rh -Rh +, Rh -Rh + Rh -
Rh factor is a protein that is found in the blood of about 85% of the population. Those who have the factor are Rh positive, while those who don't, are Rh negative. A person who is Rh negative can safely donate blood to persons with or without the protein. A person who is Rh positive can only donate to those who are Rh positive.
Father is Rh-Rh-Positive blood type has two options so mother could be Rh+Rh+ or Rh+Rh- and so :Rh-Rh- X Rh+Rh+all kids will be positivethe second option isRh-Rh- X Rh+Rh-50% of the kids will be negativethe other 50% will be positive.
Yes this depends on type off parent alleles Rh- ,,,,,,, alleles are (Rh-Rh-) Rh+ ,,,,,, alleles are (Rh+Rh+) or ( Rh+Rh-) if mother is (Rh-Rh-) and father is (Rh+Rh+ ) there is no chance to have Rh- baby, here all will be Positive if mother is A+ (Rh+Rh+) and father is O+(Rh+Rh+) also here there is no chance to have Rh- baby, and all will be Positive if mother is A+ ( Rh+Rh-) and father is O+( Rh+Rh-) the may have a negative baby but with very low percentage that reaches to 25%
5-10%. Some sources put it at 6%.
