Question

Similarities in organism with different genotype indicates

(a) microevolution

(b) macroevolution

(c) convergent evolution

(d) divergent evolution.

Answer 1

Similarities in organisms with different genotype indicates convergent evolution. Convergent evolution is the appearance of externally similar structures in organisms of different groups and this may be because they are adapted to similar environmental conditions.Most common example for this is wings of insects and birds. The two gropus that is insects and birds are from different phylas, but both posses wings which are adapted for their arial mode of habitat.

But divergent evolution is exact opposite of convergent evolution in which similar organisms posess different traits.

Microevolution and macroevolution are also relative terms but, microevolution deals with small populations that is changes in alleles within the species and macro evolution occurs within different gene pools.
