During fertilization in sea urchins,the protein bindin binds to a bindin receptor on the egg.How would the process of fertilization be affected if a mutation was present in the binding receptor?
A)The sperm would still penetrate the egg but further cell division would not occur.
B)The sperm would not bind to the surface of the egg and so fertilization will not occur.
C)The mutated receptor would allow multiple sperm cells to enter the egg (polyspermy).

The binding receptor on the egg plays a crucial role in allowing the sperm to bind to the egg and initiate fertilization. If a mutation were present in the binding receptor, it is likely that the sperm would not bind to the surface of the egg, thus preventing fertilization from occurring.
