Assuming no involvement of the bombay phenotype: a. if e girl has blood type o, whet could be the genotypes and corresponding phenotypes of her parents? b. if e girl has blood type b end her mother has blood type a, what genotype(s) and corresponding phenotype(s) could the other parent have? c. if a girl has blood type aa and her mother is also ab, what ere the genotype(s) end corresponding phenotype(s) of any male who could not be her father?

a) OO/OO (phenotype O) ; OA (ph A)/OB (ph B)  ; OO(phO)/ OA(ph A); OO(ph O)/OB (ph B).

b) OB (ph B) or BB (phB) or AB (ph AB).

c) OO(ph O)

Explanation:

a) Blood type 0 is recessive. This girls genotype is  OO.

Then, parents need to have at least one allele O each in their genotype. Possibilities genotypes and phenotypes (ph): OO/OO (phenotype O) ; OA (ph A)/OB (ph B)  ; OO(phO)/ OA(ph A); OO(ph O)/OB (ph B).

b) Blood type B is co-dominant with A. If the girl is B, it means her genotype can be OB or BB.

But we are told that  the mother has blood type A. Also co-dominant. This means the girls genotype cannot be BB.

If the girl is OB, it means she got the O allele from her mother.

The other parent then has to be responsible for the B allele. This means the father could have been OB (ph B) or BB (phB) or AB (ph AB).

c) If the girl is AB (I assume misspelling) and her mother ALSO is AB, then the father cannot be OO(phO). Because he has to give the allele A or B to the girl.  

Any other genotype is possible.

answer and explanation;

volcanic rocks are igneous rocks which form from lava, molten rock which has been thrust out of a volcano onto the surface of a rocky body such as an asteroid, planet, or dwarf planet.  

plutonic rocks are igneous rocks which form from subterranean chambers of molten rock or magma. plutonic rocks make up the base of continental crust as well as oceanic crust. their slow rate of formation causes them to be coarse grained since there is plenty of time for large crystals to form before the magma solidifies into rock.

the textural difference is that plutonic rocks are more coarse grained than volcanic rocks. plutonic rocks are coarse grained while volcanic are fine grained ; glassey or fragmental. since fine and coarse are adjectives the decision as to whether a rock is fine or coarse grained is generally made on the bases of whether or not the individual crystals can be seen in most if the rock.
