Answer 1

Hint: A family is a group of related genera. It shows similarities among individuals of different genera but shows differences among the species. Family can be used for evolutionary studies.

Complete Answer:
Similarities:
- The cats and dogs belong to the same domain eukarya, kingdom Animalia, phylum Chordata, class Mammalia and order Carnivora. They both show similarities like they can be domesticated.
- Both are carnivorous animals and can give birth to young ones. They both are related to one another by a common ancestor that is carnivore. They have sharp teeth for tearing flesh and live a life like predators. Other animals in carnivores are wolf jackals etc.
- Thus we can say both the cats and dogs have several similarities. So, Assertion is true.

Dissimilarities: Cats belong to the family Felidae and are closely linked to tigers, leopards lions whereas dogs belong to family Canidae and is closely related to wolf, red fox etc. They both belong to different families. Thus they are not related to each other. So, the reason is false.

Thus the correct answer is (c) Assertion is correct but the reason is incorrect.
