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

A number of plant species have a recessive allele for albinism; homozygous albino (white) individuals are unable to synthesize chlorophyll.

In mice colored coat is dominant to albinism. Sniffles, a male mouse with a colored coat is mated to Esmeralda, an alluring albino. The resulting litter of six young all had colored fur. The next time around Esmeralda was mated with Whiskers, who was the same color as Sniffles; some of this litter were white. a)What are the probable genotypes of Sniffles, Esmeralda, and Whiskers? b) If a male of the 1st litterwas mated to a colored female of the 2nd litter, what phenotypic ratio might be expected among the offspring? c)What would be the expected results if a male of the 1st litter was mated to an albino from the 2nd?
