Her hair. Their eyes. Their facial features. Your susceptibly on an error. They are all derived from your parents in the form of genes. In recent decades, it has an explosion of research dealing with genes, heredity and genetics. Research has shown that genes play an important role in both how we look and how we act. If you are interested in learning more about genes and dominant genes, read this article. In the article we are discussing which is a gene, how genes work and which have a dominant gene means.
Before we can learn what is a dominant gene, we must first learn what is a gene. For this purpose must we go back to the biology basics. As most people know, people from DNA (deoxyribonucleic acid) are together. DNA consists of 46 chromosomes. In our bodies, each of these chromosomes are linked (to 23 pairs of chromosomes). Where are these chromosomes? Come from our parents!
The father consists of 23 pairs of chromosomes sperm and egg mothers consists of 23 pairs of chromosomes. Therefore, you get half of your chromosomes from your mother and half from your father. The 23 chromosome is the sex chromosome (men will get an x chromosome from the mother and a y chromosome from the father chromosomes, while females 2 X). The other chromosome 22 pairs (also called alleles) determine other characteristics such as color of hair and eye.
So, now that we are what genes know what are dominant genes? The genes we inherit from our parents can be either dominant or recessive. If we inherit two recessive genes, we inherit one recessive inherited. As well, if we inherit two dominant genes, we inherit one dominant inherited. Dominant genes, beat ' always ' recessive genes. Therefore we would be a dominant gene of a parent and a recessive gene inherit from the other, we shall end up dominant inherited with a.
Let us use hair color as a more concrete example. Dominant genes are associated with brown hair. Recessive gene associated with blond hair. They thus have a child of blond hair have 2 recessive genes (one from each parent) inherit. Could a child with brown hair, but be born if it inherited 2 dominant genes, or if it is a dominant and a recessive gene inherited (because the dominant gene the recessive genes trumps).
What are other features, excluding the brown hair, associated with dominant genes? Dominant genes also curly hair, pits, vision, are associated with lips thick, and is double linked.
Find out more about dominant and recessive traits, perform an online search or head to your local library. There are a lot of information around the concept of genes. What is this article is just the beginning. Learn you more today determine what features you have inherited through dominant and recessive traits of your parents!
