Why are some people born with Rh-positive blood while others are born with Rh-negative blood..

Answer / baba_mailme

Rh factor is a protein on the surface of red blood
corpuscles in many persons.It was discovered in 1940 by
Landsteiner and Wiener in the blood of rhesus monkey, hence
its name. Majority(85 to 99%)of the people have this factor
and are classified as Rh positive(Rh+). Others who lack
this factor are classified as Rh negative(Rh-).Formation of
this protein is controlled by a dominant gene designated
as R. Thus RR (homogyous dominant)and Rr(heterogyous
dominant)persons are Rh positive,and rr (homogyous
recessive)persons are Rh negative. Both the individuals are
phenotypically normal. The trouble arises when the blodd of
thetwo mixes up or during pregnancy

The weight of the fruit of one variety of squashes is determined by three pairs of genes: AABBCC produces 6 lb squashes and aabbcc produces 3 lb squashes. Each dominant allele adds 1/2 lb tothe base weight (3 lb). If a pure breeding line that produced 6 lb squashes was crossed with a pure breeding line that produced 3 lb squashes, what would be the phenotypic ratio of the F1 and the F2?
