50% bands similar to father and 50% similar to mother DNA fingerprint pattern

100% similarity to both the parents DNA fingerprint as both contribute equally to zygote formation

100% similarity to mother’s DNA print because of maternal inheritance

100% similarity to father’s DNA print due to large number of mitochondria in sperm

Non competitive inhibitors often bind to the enzyme irreversibly

Competitive inhibition is seen when substrate competes with an enzyme for binding to an inhibition protein.

Competitive inhibition is seen when the substrate and the inhibitor complete.

Non competitive inhibition of an enzyme can be overcome by adding large amount of substrate.
