In regards to Blood Type, Phenotype O refers to Blood Type O as opposed to A, B, or AB.
B.
YY is phenotype Yy is not yy is a phenotype
the appearance of an organism is it's phenotype
The phenotype of the organisms. The physical and behavioral traits of the organism.
phenotype.
Yes. The genotypes of the father could be BO or BB (Phenotype = B) The genotype of the mother is OO(Phenotype = O) Mating these genotypes will produce either OO (Phenotype O) or BO (Phenotype B) In short, children from these parents are B or O The Rhesus(D) positive was inherited from the father.

The gene for blood type O is recessive. The mother can only have the phenotype O if she has the genotype OO. The gene for blood type B is dominant, the father has the phenotype B, but can have the genotype BB or BO. If the father is genotype BB, the child will be B + O = BO genotype; hence B phenotype. If the father is genotype BO, the child can be B + O = BO genotype; hence B phenotype (50% chance). Or O + O = OO genotype (O phenotype, 50% chance). * Phenotype = displayed trait that can be found with a simple blood test. * Genotype = genetic make up (one part from each parent), this requires a DNA test to be confirmed; however, it can sometimes be deduced by logic.
A patient with O negative blood is considered the universal donor. This phenotype is associated with just one genotype; both alleles must be "O" and both alleles must be negative.
50%. First you need to remember that a BO genotype would result in a B phenotype. The only way to have an O phenotype is to have an OO genotype. Therefore, we know that John's parents are BO and OO. Then, you can make a Punnett square. B O O BO OO O BO OO Half of the offspring between John's parents would have genotype BO and half would have OO. Therefore, half would have each of the phenotypes B and O. The answer is 50%.
B.
Yes. The father's phenotype is AO+*; the mother's is OO--.
No. For the child to have a phenotype of O, they require an oo genotype. As the mother cannot provide one O to this, this is not possible.
genotype or phenotype
Yes, if both parents have the genotype AO, then the child can have the O from both parents, phenotype O
