2. A man with type B blood marries a woman with type A blood. Their first child has type o blood. The couple says this is
impossible, and requests that the family be retested for their blood type.
a. Is it possible for these two people to produce a type o child?
b. What are the genotypes of both parents?
c. Draw a Punnet square to show the possible blood types of their children.

A) it is possible if they both have the recessive O type

Yes it is possible

Explanation:

I cannot get you a punnet square but...

Mother: Type A blood = 1 part A blood 1 part O blood = OA

Father: Type B blood= 1 part B blood 1 part O blood = OB

There is a 25% chance for O blood

There is a 25% chance for AB blood

There is a 25% chance for OB blood

There is a 25% chance for OA blood

The Act introduced a number of measures to reduce air pollution, especially by introducing "smoke control areas" in some towns and cities in which only smokeless fuels could be burned. By shifting homes' sources of heat towards cleaner coals, electricity, and gas, it reduced the amount of smoke pollution and sulphur dioxide from household fires. Reinforcing these changes, the Act also included measures to relocate power stations away from cities, and for the height of some chimneys to be increased.
