Statement C is true
Statement A false because all have carbohydrate trees
Statement D false because Mutations results in O type of blood group
Statement B false because there is no different sugar attachment

Human blood types A, B and O are associated with the carbohydrate antigens A, B and...
Human blood types A, B and O are associated with the carbohydrate antigens A, B and H respectively. A and B antigens are caused by an alteration of H antigen. Normally everyone can synthesize H antigen (a cell surface carbohydrate found on red blood cells and other cell types). Some people make A and/or B transferase(s) which converts the H antigen to an A and/or B antigen respectively. The H antigen is produced by a specific fucosyltransferase encoded by the...

A mutant plant with white flowers exists that lacks red anthocyanin pigment, normally made by enzyme P. Indeed the petal tissue lacks all detectable activity for enzyme P. Despite the lack of enzyme activity, a study of homozygous mutant cells using antibodies against the wild-type enzyme demonstrated that the cells homozygous for the mutation still had the enzyme (i.e., the antibody showed the presence of the enzyme). Which statement below could most likely explain these results? A )The mutant had...

There are four types of blood: A, B, AB, and O (Figure 4). Each
is characterized by the glycoproteins (proteins with a sugar
attached) and lipoproteins (proteins with a lipid attached)
embedded in the surface of red blood cells (RBCs). In addition to
type, blood can be rhesus (Rh) factor positive or negative.
These proteins are inherited and may differ from individual to
individual. If, during a transfusion, an individual receives
blood with the incorrect RBC proteins (for...

With respect to genetics, ABO blood types are controlled by a single gene designated I, which has three alleles. The I A allele gives blood type A, I B gives blood type B, and i gives blood type O. The I A and I B alleles are codominant and i allele is recessive to both the I A and I B alleles. Aside from the I alleles, there are two other genes that when mutated affect ABO blood type inheritance....

Of the four different blood types (O, A, B, AB), 43.4 percent of people have type O blood, 40.7 percent have type A blood, and 10.5 percent have type B. What percentage of people have type AB blood? Answer:

Rh is the most complex of the blood group types, involving at least 45 different antigens. The most clinically important antigen, D or RhO, is encoded by the gene RhD which is found on chromosome 1. Individuals that are Rh-positive have either one or two RhD genes, whereas the Rh-negative phenotype is caused by the absence of the RhD gene. (The antithetical allele d does not exist, however the letter "d" is used to indicate the D-negative phenotype). For the...
