Predict what event would likely to occur if a sperm contacted an egg of another species? a) Sperm head and egg membranes would not fuse because the binding of a sperm head to a receptor on the egg membrane is species-specific.

b) Acrosomal reaction fail to occur because membrane protein of sperm head is not complementary with receptor on the zona pellucida between gametes of different species.

c) Binding between sperm and egg of different species may occur because the binding of a sperm head to a receptor on egg membrane is species-specific.

d) Cortical granules will release enzyme to destroy sperm receptor and harden the zona pellucida
