Answer:

T-cells and B-cells together make antibodies. It may take a couple days for these to start to produce after the virus is already in your system. These antibodies stick to antigens to alert the rest of the body where it is. The body then makes toxic substances to fight the virus.

Breeding a yellow dog and a brown dog produced puppies with both brown and yellow hairs intermixed. This is an example of what?
mylen [45]

Breeding a yellow dog with a brown dog produced puppies with both yellow and brown hairs intermixed. This is an example of codominance.

<h3>Codominance:</h3>

When a heterozygote expresses both alleles of a gene pair, this type of inheritance is known as codominance. As a result, the offspring's phenotype combines the phenotypes of its parents. The characteristic is, therefore, neither recessive nor dominant. The codominance of people is illustrated by those with type AB blood. Because I^A and I^B are codominant and will be expressed jointly as a result of this, a person who inherits both of these alleles will have type AB blood.

The phenotype of the offspring is a combination of the phenotype of the parents. The crimson flower with white spots on it and creatures with black and white coats are two further examples of codominance.
