Hair texture (straight, curly, or wavy) and color (blonde, brown, etc.) are influenced by genetic inheritance from both parents, but the dominant genes for hair type often come from the father.
A baby’s facial structure, including the shape of the jawline, nose, and eyes, can be a blend of both parents’ genes, with certain traits like a strong chin or prominent cheekbones more likely to come from dad.
A significant portion of a child's height is determined by genetics, and both parents contribute to this trait. However, studies have shown that the father’s height might have a stronger impact in certain cases.
While oral health can be influenced by both parents, a child may inherit traits related to tooth alignment, enamel quality, and susceptibility to dental issues from their father’s genes.
Research suggests that cognitive abilities like math skills can be influenced by the father’s genetic contribution, particularly from the Y chromosome, which plays a role in brain development.
The father contributes to the baby's eye color through the genes he passes on. Eye color is determined by a combination of both parents' genetic information.
Foot size is largely determined by the genetic contribution from both parents, but fathers tend to pass down larger foot sizes due to the influence of their height and build.
