That's why those uncommon instances are called monozygotic twins: the 2 kids are fashioned with the aid of using the identical gametes, inherit the identical genes, and consequently have same DNA check results.DNA replication is semi-conservative.
This approach that every new molecule of DNA incorporates one strand of the determine molecule and one complementary strand this is newly synthesized (daughter strand).
