The blood Group of Mother is O. The Blood Group of the Child is B. Man Exonerated If He to Blood Group?

aalyn [17]

Answer:

If the mother's blood type is O, and the child's blood type is B, a man would be exonerated from paternity if he has blood type A or O.

Explanation:

In the above case, if a mother has blood type O and her child has blood type B, a man can be exonerated from paternity only if his blood type is A or O, and responsible if he is type B or AB.

The blood type is defined by the presence of surface antigens in the red blood cell, called A and B. The presence of each antigen is determined by a gene present on the parental chromosomes.

Blood type A corresponds to the presence of gene A, and its genotypic expression can be A/A or A/O.
Type B blood, whose genotype is B/B or B/O, is due to the presence of a gene containing the B antigen.
AB blood —due to codominance— has one gene for A and another for B, with genotype A/B.
Blood type O, characterised by the absence of surface antigens, behaves like a recessive trait, which only manifests itself in the absence of surface antigens A and B. The genotype is O/O.

By making a hypothetical crossing between mother and man, one can observe why he can be exonerated.

Man with blood type O

♂ O|O

♀ O|O

Alleles O O

O O|O O|O

The only possibility, in this case, is to have children with type O blood. No chance of children B.

Male with blood type A

♂ A|O

♀ O|O

Alleles A O

O A|O O|O

In this case there is a 50% chance that the children will be blood type A and 50% chance that they will be O. No chance of children B.

In the case of a man A|A the result is 100% probability of children A|O, and no probability of children B.

So, a man with blood types A (any genotype) and O, can be exonerated from paternity, since it is impossible for him to have a child of blood type B, when the mother is of blood type O.

Carbon and hydrogen have similar electronegativities and combine together to form hydrocarbon molecules. What type of bonds form

egoroff_w [7]

The type of bond formed between carbon and hydrogen is NON POLAR COVALENT BOND.
Covalent bond involves sharing of atoms between two elements; each element will donate electrons which will be equally shared by the elements involved. In the case of carbon and hydrogen, carbon has four electrons in its outermost shell, therefore it will form a covalent bond with four atoms of hydrogen each of which will donate one electron.

How many different offspring genotypes are expected in a trihybrid cross between parents heterozygous for all three traits when

aalyn [17]

Answer:

27 genotypes and 8 phenotypes

Explanation:

Supposing that the genotypes of both of the parents are AaBbDd (A, B and D are dominant over a, b and d). After completing the Punnett square, you can predict the following offspring:

I add an image where you can see all the 27 genotypes and frequencies.

Finally, all the 8 phenotypes with the following frequencies:

27/64 A-B-D-

9/64 A-B-dd

9/64 A-bbD-

9/64 aaB-D-

3/64 A-bbdd

3/64 aaB-dd

3/64 aabbD-

1/64 aabbdd

Total 64/64

Note: when a phenotype is A-, it means that it came from either genotype, AA or Aa. The same applies to B- (BB or Bb) and D- (DD or Dd)

Channel proteins that form a narrow passageway in gap junctions are known as which of the following

NeX [460]

Channel proteins that form a narrow passageway in gap junctions are known as connexons

Connexons are assemblies of six proteins that form a pore or a narrow passageway between the cytoplasm of two adjacent cells.
These passageways allow the bidirectional passage of iron and signals between the cells.
