Question

differentiate between homologous and analogous

Answer 1

homologous are those organs which have same structure but different function. Eg bird limbs and our hands they both have same structure but are modified to perform diff. functions.
Analogous are those organs which have different structures but same function. Eg. wings of bat and wings of birs they both have diffrent structure but same function (help in flying)

Answer 2

homologous are similar in their anatomy and different in functions and vice versa for analogous
