Heterologous:

2. The genes that differ in origin and activity are referred to as heterologous genes.
3. They are unique in terms of sequence and activity.
4. Similarly, anatomical structures that developed from different ancestral lineages are termed heterologous or analogous.
5. They have the same function but differ in structure and origin.
