We often hear people talk about family traits and how they seem to skip a generation, according to Mendel what has happened?
Vesnalui [34]
This family trait that skips a generation comes from an autosomal recessive trait or as Mendel called as hidden non-dominant trait. Offsprings have a dominant and recessive trait which comes from both parents. Recessive trait appears only when two offspring with same recessive trait blends. This happens in self-fertilization. In the human population, marriage is prohibited between offsprings, thus having recessive trait is only imminent when cousins are married.

The antigen-binding sites of an antibody molecule are formed from the molecule's variable regions. why are these regions describ
tino4ka555 [31]

The antigen-binding sites of an antibody molecule are formed from the molecule's variable regions which are described as so because their amino acid sequences can be different on different antibodies.

The specificity of antibodies is determined by the variable regions found at their endpoints. Antibodies are specialized proteins secreted by B-cells of the immune system. They are also called immunoglobulins. They contain four polypeptide chains that comprise two heavy chains and two light chains to form a Y-shaped molecule.

The variable regions, more specifically the hypervariable regions of an antibody, have a high ratio of different amino acids with the most common amino acids provided in one place. The variable region serves as the antigen-binding site while the constant region found below the variable region is determined to invade the antigen.

Antibodies are preserved in our body to identify the antigen the next time it encounters. They send the signals to the other body parts to reject the antigen and invade it.

To know more about variable regions of antibodies, refer to the following link:
