It is much more common for children to have dark eyes since this is the dominant gene. For a child, having light eyes is less common because it is a recessive gene, and it takes influence on both sides of the family.
However, a dominant gene with dark eyes will win over the recessive gene in most cases. This means that if the father has dark-colored eyes, it is likely that his child will too.
2. CARDIAC PROBLEMS
All fathers carry a gene that can be transmitted to their son, which can increase their risk of heart attack by up to 50%. This specific gene prevents the control of inflammation in the body, which means that it is much more common that the arteries obstruct and block the flow of blood to the heart.
Jen Stagg, a naturopath who specializes in guiding patients to a healthy lifestyle, has conducted a backup study, which found that men with haplogroup IY chromosome are 50% more likely to have an illness. cardiac and pass it on to their son.
If a man is infertile, there are ways around this problem. Men can participate in in vitro fertilization to have a child, but if they do, they can still make their son more likely to be infertile.
In a study of the Journal of Human Reproduction, it was found that men who had been conceived by IVF had a lower sperm count than those who had been conceived naturally.
This indicates that fathers are transmitting fertility problems to their children. Although the results are not entirely conclusive, this shows that it is likely that a father’s fertility problems are transmitted from generation to generation.
4. THE SIZE
With more than 700 gene sequences involved in determining the size of a child, it may be easier to say that men and women play a role in the size of the child. These gene variants can make a significant difference, it can affect the equivalent of the size of an entire inch.
Sometimes a rare variant of the gene sequence can dramatically affect the child, causing him to switch to his father’s size rather than his mother’s or a combination of both. In this way, the man can have a slight effect on the size of his child.
5. THE GENDER
The father always determines the gender of the baby. Since men are in possession of both an X and a Y chromosome, women only have Xs, depending on whether X and Y chromosomes are transmitted. A man’s sperm carries only one X or Y chromosome at a time, which means that the genus depends on the dominant spermatozoa.
It is also thought that a man’s family tree can be used to gather information about whether his child will be a boy or a girl. Although this is only an assumption, the assumption is fact-based and often presents a model in genetic history.
Although nothing else is known yet, the researchers are looking into an unknown gene that could influence a man’s X and Y chromosome numbers in his sperm, which could make a particular genus more likely in each family.
If you have concerns about your child’s genetic future, it may be helpful to consult a genetic counselor. They can help you determine if your child is at risk of serious harm. This action can be performed if you have concerns about a child already born or if you are planning a pregnancy.
6. MENTAL HEALTH ISSUES
It is well known that mental health problems can be rampant in the family, but if you have an older father, you may be more likely to have specific mental health problems. Generally, older men with schizophrenia or ADHD are more likely to pass on their problem to their children because of changes in their DNA as they age.
Older men are therefore four times more likely to transmit mental health problems because their sperm will contain their mutant DNA, which can lead to more complex problems.
Why does not mothers’ DNA change with age? In fact, it changes. The difference is that women’s eggs are with them since birth, and therefore do not change. While men’s sperm is produced all the time, a woman has limited eggs, and they do not change much.
However, older women are more likely to give birth to children with autism, and rare problems with genetics.

7. DENTAL PROBLEMS
If a father has a lot of problems with his teeth, it is very likely that his children are suffering from the same thing. Everything about the mouth depends on genetics, including the size and shape of the jaw and teeth.
Women can also transmit their teeth and jaw. However, men’s genes tend to be more dominant in dental health because the gene that affects them is more active. Source:
