Beatrice Knight, a Research midwife, told BBC. “We have confirmed that a father’s height also has a direct impact on their baby’s growth, with taller dads having longer and heavier babies,' Dr. It appears that fathers determine the baby’s height more than mothers according to studies. This is why the majority of people in the world have brown eyes. RELATED: Can You Get A DNA Test When The Baby Is In The Womb? For example, brown eyes are the dominant gene for eye color, and blue eyes are recessive, so when the genes for brown and blue eyes are combined in offspring, there is a 75 chance that the offspring will have brown eyes. Nonetheless, you might find that the baby grows up to be way taller or shorter than both parents.

For female babies, subtract 2 inches from the average of the parents’ height. For male babies, add 2 inches to the average of both parent’s height. However, you can estimate a baby’s adult height using the mother’s and father’s height. Keep reading to discover the most common dominant and recessive traits that babies are likely to inherit. It is called polygenic inheritance, and as such, it explains why there are so many variations in people’s features. A contribution of many genes influences them. These traits majorly determine how the baby looks.īody features are not controlled by one gene. Therefore, concluding in my belief that having a cleft chin is a recessive trait. The recessive trait has to be paired with a similar recessive trait for it to be expressed. Hypothesis: Based on the students I see on a daily basis, specifically talking about the different people in my classes, I had noticed there was a least am ount of people with cleft chins, then without. The stronger trait is the dominant trait, and the other, the recessive trait. When the two alleles are different, the stronger trait will be expressed. The alleles control the traits of the baby. The two parts of a gene are called alleles. A gene has two parts one part comes from the mother’s chromosomes, and the other from the father’s chromosomes. Will your baby look like you? Well, it depends on genetics.
