The man couldn’t have fathered the following child.
<u>Explanation:</u>
The blood grouping system in humans is called ABO blood grouping. The possible blood groups of humans are A,B,AB and O. ABO blood grouping is an example of co-dominance where both alleles of the ABO gene are expressed equally.
The ABO gene has 3 alleles. They are I^A,I^B and i. the alleles I^A,I^B are dominant over i. Person with the genotype I^A I^A and I^A i has the blood group A while a person having the genotype I^B I^B and I^B i has the blood group B. The person with the blood group will have the genotype I^A I^B.
Here the mother’s blood group is O which means her genotype is ii. The man’s blood group is AB which means his genotype is I^A I^B. The possible genotypes of the children are I^A i,I^A i,I^B i,I^B i with respective phenotypes A, A, B and B.
There is no possibility that the child can have the blood group O which means that the man could not have fathered the child.
<span>There are two
types of modern wind turbines. In a Verical-axis wind turbines (VAWTs), the
shaft is mounted on a vertical axis perpendicular to the ground. They are
aligned with the wind so there’s no adjustment necessary when the wind
direction changes. It can’t start moving on itself that is why it needs a boost
from its electrical system to get started. It uses wires for support so the
rotor elevation is lower. They are less efficient than HAWTs due to its lower
elevation. Lower elevation means slower wind due to ground interferences. The other
type is Horizontal-axis wind turbines (HAWTs), the shaft s mounted horizontally
parallel to the ground. It is constantly aligned with the wind using a
yaw-adjustment mechanism. This mechanism moves the entire rotor left or right
in small increments. It uses a tower to lift the turbine components to an
optimum elevation for wind speed and take up very little ground space. It is
much more efficient than VAWT. </span>
