Do you often wonder why a child resemble their parents?
The characteristics of individual beings are passed from one generation to the next in their chromosomes. But it doesn't mean that a person lost it's uniqueness. Each of our parents gives us 23 chromosomes, making 46 in all. That means that we have two versions of our genes, but one is often dominant. We can see the effect of a dominant gene, but the recessive gene is still there and can be passed on to our children.
What are these chromosomes? Chromosomes are tiny threads that are present in all cell apart from our red blood cells. They contain all the information from an en tire person to develop. There is a special pair that actually determines a persons sex.
Short sections of a chromosomes are called genes. Each genes carries the instructions for a specific characteristic such us an eye color, hair color, height and etc. Many of these genes work with other genes, so it is not easy to say what effects they will have. At the moment the mother's egg is fertilized, the genes starts issuing instructions for the molding of a new human being. Every characteristics that we inherited from our parents will be passed through the coding of the genes within the chromosome and will be passed down to the next generation.
Fact: The gene for brown eyes is the dominant gene. Two brown eye
genes give brown eyes, one brown gene and blue gene usually
give brown eyes. Two blue eyes genes give blue eyes.
