They exist because all these genes have descended from the genes of common ancestors.
Proteins
There can be billions types of possible antigens and only 20,000 to 25,000 genes are present in body. So the answer is NO.
No - the father's genes are not always the dominant genes.
Chromosomes contain genes which are segments of DNA.
They exist because all these genes have descended from the genes of common ancestors.
They exist because all these genes have descended from the genes of common ancestors.
Proteins
Alleles are genes that exist in multiple forms.

So that our cells will know how to make the proteins that they must make to exist.
Without genes, you wouldn't exist! Genes are the body's plan of life. Our cells consult genes on what should be built in your brain.
Genes are the things that make you you. They come in 23 pairs and they decide lots of things like what colour your hair, eyes or skin is and whether or not you're colour blind. Each cell contains a full set of these and if you didn't have them, you wouldn't be here. You wouldn't exist. No life would exist, even plants.
This will depend on the animal. These kinds of animals are ones that have foreign genes inserted into them.
There can be billions types of possible antigens and only 20,000 to 25,000 genes are present in body. So the answer is NO.
Living things have the capability to produce offspring to pass on their genes, and the ability to respond to changes in the environment they exist in.
Polygenic inheritance occurs when one characteristic is controlled by two or more genes. Often the genes are large in quantity but small in effect. Examples of human polygenic inheritance are height, skin color, eye color and weight. Polygenes exist in other organisms, as well.
