What Affects Baby’s Genes?
Expectant parents are likely to be curious to find out what their child will be like – not only in character, but in appearance as well. Is he tall or short? What color are his eyes? Is her hair dark or light? There are a huge number of questions. But what ultimately affects a baby’s genes?
The effect of genes and the environment
The phenotype, or the expression of an individual, is the result of the interaction between the environment and genes. It is the sum of all the observable anatomical, physiological, biochemical, and behavioral characteristics of an individual.
The environment cannot alter certain genes, such as genes that affect an individual’s physical appearance. This means that if, for example, genes determine the color of a child’s eyes to be green, it doesn’t matter if the child is born in China, Senegal or Argentina – his eyes are still green.
Time and environment can modify certain genes, but they may not manifest in practice. On the other hand, the environment influences the expression of certain genes that shape an individual’s personality.
For example, some genes may expose an individual to tobacco or alcohol use, while others are more manageable. They are directly affected by the environment.
Gene registration
Parental genetics determine a baby’s genes, which determine, for example, a child’s eye color, hair thickness, nose shape, and leg size. All information is stored in genes, or hereditary factors.
The child receives half of the genetic information from his father and the other half from his mother. So why does a child look more like another parent? Each gene consists of two copies, one from the mother and one from the father. The quality seen on top is dominant over the other
Genes can be divided into dominant or dominant and recessive. The former are the strongest, i.e., they are more likely to define certain characteristics. Recessive genes are weaker, but still exist, and certain traits may appear generations later.
What color are the child’s eyes?
Researchers have long thought that only two genes affect the color of human eyes. However, advances in technology have made it possible to study the human genome in more detail, and today it is known that at least eight genes affect the eyes. It is known that brown is the predominant color in relation to green and blue, while green is predominant in relation to blue.
What color is your child’s hair?
Years ago, researchers identified 12 different genes that affect hair color, making up a total of 45 color, shape, and type variations. Dark hair is the dominant gene and light recessive gene.
In order for a child to have red hair, his or her parents must have this gene recessive, in addition to which the two alleles must have information about red hair. Such a situation is very rare.
What affects a baby’s genes the most?
The environment affects the baby’s genes and especially how the genes eventually manifest in practice. For example, a child may have a genetic tendency to grow tall and slender, but if he eats poorly during his childhood, he may never grow tall.
The environment has the ability to favor the expression of certain genes or, alternatively, to hinder their expression. It is part of the parents ’job to help the child enjoy their life with the genes that have been passed on to him.
