A) more likely to inherit schizophrenia
B) more likely to inherit depression
C) more likely to inherit autism
D) less likely to inherit disorders
Monozygotic Twins
Twins that are genetically identical, resulting from the division of a single fertilized egg into two.
Dizygotic Twins
Dizygotic twins, also known as fraternal twins, are two offspring that result from the simultaneous fertilization of two different eggs by two different sperm, leading to genetically distinct siblings.

Final Answer :
D
Explanation :
Dizygotic (fraternal) twins are less genetically similar than monozygotic (identical) twins, as they only share about 50% of their genes, similar to ordinary siblings. Therefore, they are less likely to inherit the same genetic disorders compared to monozygotic twins, who share nearly 100% of their genes.
