Question

What blood type does a child inherit?

Answer 1

Blood is a bodily fluid in humans and other animals that carries metabolic waste products away from cells while delivering vital elements such as nutrition and oxygen to them. As a result of its genesis in the bones and the presence of fibrinogen, blood is regarded as a specialised type of connective tissue in anatomical and histological terminology.

Complete answer:
Some blood types are defined by the presence or absence of specific foreign compounds known as antigens, which can cause an immunological response if they are introduced into the body. Safety in blood transfusions is dependent on thorough blood sampling and cross-matching since some antigens might cause a patient's immune system to attack the transfused blood.
The occurrence and absence of two antigens – A and B – on the surface of red blood cells determines the four main blood types. Aside from the A and B antigens, there is indeed a protein found which is called the RH factor, that can be either present (+) or missing (–), resulting in the creation of eight most frequent blood types which are A+, A-, B+, B-, O+, O-, AB+, AB-. Each blood type varies from one another.
Each biological parent gives their child one of their two ABO alleles. A mother with blood type O can only pass on an O allele to her child. A parent with blood type AB may transmit on either an A or a B gene to his son or daughter. This pair might produce children with blood type A (O from the mother and A from the father) or blood type B (O from both parents).
As there are four distinct female blood types linked to the mother and four different paternal blood types, hence there are 16 potential pairings to consider while determining a child's blood type.

Note:
Blood is a mixture of liquids and solids. The liquid component, known as plasma, is composed of water, salts, and protein. Plasma makes up more than half of your blood. Red blood cells, white blood cells, and platelets are all found in the solid component of your blood. RBCs transport oxygen from your lungs to your tissues and organs.
