Answer:
Explanation:
Dominant traits are traits that are visible in the phenotype of an organism.
If barking is dominant in some allele of the dog and it has both male and female then a cross between the male and female with the dominant allele for barking will give a strain of pure breeder barkers.
A recessive allele cannot breed a pure barker because it does not have the allele for barking.
Hence a cross between two individual that dominos of the allele will breed true type.

Carbohydrates, such as sugar and starch, for example, are readily broken down into glucose, the body's principal energy source. Glucose can be used immediately as fuel, or can be sent to the liver and muscles and stored as glycogen.
