Which of the following traits of a dog is inherited from its parents?
A
the presence of fleas in its fur
B
the color of its fur
C
the ability to sit up and beg
D
the habit of barking to go outside
Explanation: 

Detailed explanation-1: -Fur color, pattern, and eye color all are inherited from the parents of an animal.

Detailed explanation-2: -When conceived, a dog receives two copies of DNA-one from the father and one from the mother. Which pieces of DNA a dog inherits from each parent is completely random. Within each strand of DNA are genes. And these genes determine traits such as coat color, ear type, tail style and more.

Detailed explanation-3: -The traits with the highest rates of heritability-in other words, those that seemed to be most influenced by genetic factors rather than environmental ones-were behaviors such as trainability, predatory chasing, stranger-directed aggression and attention seeking.

Detailed explanation-4: -Genes Rule The color of a dog’s coat is basically at the mercy of his gene pool. Genes do two things that determine a dog’s appearance. They control the pigments produced (eumelanin and phaeomelanin) and where these pigments are produced.
