Codominance means that neither allele can mask the expression of the other allele. An example in humans would be the ABO blood group, where alleles A and alleles B are both expressed. So if an individual inherits allele A from their mother and allele B from their father, they have blood type AB.
Answer:
Individuals that cannot produce the H substance appear to be type O even if they have functional A and/or iB alleles.
Explanation:
The H antigen is a precursor to the ABO blood group antigens, present in people of all common blood types. The Bombay phenotype (hh) does not express antigen H on red blood cells.The person with blood group O contain the H antigen but it remains unmodified remains unmodified.
Answer:
Yup it is made of neutrons itself composed of both neutrons and glial cells
A signal cascade is a series of chemical reactions which are triggered by a stimulus acting on a receptor that is then transduced to the intracellular space through second messengers. Finally, effector molecules receive the signal causing a cellular reaction to the initial stimulus. A signal cascade is very useful because it facilitates and accelerates the communication between cells that could be in different parts of a living organism. This communication is vital for cell processes in complex multicellular organisms.
