In the ABO series, the gene for blood type O is , while A and B are genes, and AB is .
Nesterboy [21]

Answer:

Gene for blood type O is recessive

Gene for blood type A and B is dominant

Gene for blood type AB is neither dominant nor recessive but a form of co-dominance

Explanation:

In the ABO blood group,  

A and B are dominant genes, O is recessive genes.  

So the different genotype and its corresponding phenotype is as follows –  

Genotype    Phenotype

AO     A

BO     B

AB     AB

AA     A

BB     B

OO     O

Hence, the two alleles AB occur and express together. Therefore, AB blood group is an example of co-dominance.  

Blood type also varies with the presence of Rh factor. If Rh factor is present, the blood type will represented with a “+” symbol. And if Rh factor is absent, the blood type will be represented by “-“symbol.

  • The forces are so power full that they can bring the sediments of ocean to level or elevation above the sea level and can have a destructive effects for the living being. As there are various causes for folding and faulting of these layers,some of these forces are given below;

Explanation:

<u>Geological events causing the folding and faulting-</u>

<u>Tectonic Plates movement-</u> The parts of the Earth layer are always sliding over each other, and when they do they produce huge seismic waves. Which then causes the earthquakes, the folding and faulting of these layers.

<u>Volcanic eruptions : </u>It happens rarely as the number of gases and lava from inside the Earth, down from the crust move upward and erupts, producing dust in the atmosphere.

The other two geological causes are;

  • <u>Intrusive igneous activity,</u>
  • <u>subduction.</u>
