Question

23. A dog breeder can determine that the sudden

Answer:

(4) is bred and the trait is capable of being  inherited

Explanation:

Mutation generally refers to a sudden change to the DNA sequence in the genome of an organism.

Since, DNA is the molecules responsible for heredity and the inheritance of traits by offspring from their parents, a mutation should be inheritable.

Hence, if a sudden appearance of hairlessness in one of the puppies is observed by a dog breeder, he/she can effectively conclude that the situation is caused by a mutation if the affected dog is bred with another dog and the hairlessness is observed in any of the resulting progeny.

Option 4 is the correct option.
