So why is it that just the first baby looked like him? An article in Scientific American explains how the entire theory of newborns looking like their dad due to evolution and fathers recognizing their offspring at birth and during caveman days isn't true – according to current studies.
A similar study in 2004 with a much larger sample size found that, in fact, most infants resemble both parents equally.
In fact, newborns, both girls and boys, look more like their mothers until they are one year old and then like their fathers. Of course, there are still many mysteries to be solved concerning the mechanisms leading to resemblance.
And since all the sperm cells come from the father, which children might resemble him more is most likely due to which paternal genes were passed along in any given child's DNA, which genes were more dominant, and which traits are more noticeable.
DNA. Everyone knows that DNA is what determines your baby's appearance. But DNA is a very complex subject. Everything from hair color, eye color, height, and weight to the placement of dimples or freckles can be dictated by you or your partner's (or both!)
Genetically, you actually carry more of your mother's genes than your father's. That's because of little organelles that live within your cells, the mitochondria, which you only receive from your mother.
Contrary to popular belief, there is no scientific evidence that suggests all firstborn daughters necessarily resemble their fathers.
Because boys have the sex chromosomes XY, they must inherit their Y chromosome from their father. This means they inherit all the genes on this chromosome, including things like sperm production and other exclusively male traits.
Specifically, the research shows that although we inherit equal amounts of genetic materials from our parents – i.e., the mutations that make us who we are instead of some other person – we actually “use” more of the DNA that we inherit from our fathers.
It is scientifically proven that genetics cause people to look and behave more like their dads than their moms. In fact, as a woman, you might have frequently been told throughout your life that you look like your father.
Unlike nuclear DNA, which comes from both parents, mitochondrial DNA comes only from the mother.
In fact, dad's contributions to their baby boy's genes make up sixty percent of the kiddo's looks. Mom's contributions only influence the other forty percent, which explains a lot in terms of baby boys looking like identical, miniature copies of their daddies!
Babies inherit multiple pairs of genes from each parent that play a role in appearance. These genes determine hair color as well as eye color and complexion. And although scientists have yet to determine how many genes ultimately determine the exact color of a child's hair, they do understand how the process works.
Mothers tend to always see the baby's father in their newborn, and fathers tend to see it, too – especially with firstborns. It's the outsiders, the extended family and friends who see otherwise. I believe that this evolutionary theory is still very much true.

Winning by a Nose
Two large-nosed parents are likely to produce a large-nosed baby, and two small-nosed parents to produce a small-nosed baby. However, when a large-nosed father produces a child through a small-nosed mother, the baby can have a medium-sized nose, due to incomplete dominance.
The egg and sperm each have one half of a set of chromosomes. The egg and sperm together give the baby the full set of chromosomes. So, half the baby's DNA comes from the mother and half comes from the father.
Most people feel as though they look more like their biological mom or biological dad. They may even think they act more like one than the other. And while it is true that you get half of your genes from each parent, the genes from your father are more dominant, especially when it comes to your health.
Your children inherit their eye colors from you and your partner. It's a combination of mom and dad's eye colors – generally, the color is determined by this mix and whether the genes are dominant or recessive. Every child carries two copies of every gene – one comes from mom, and the other comes from dad.
Virtues such as honesty, integrity and tolerance are most likely to come from mothers while courage, laziness and a good sense of direction come from fathers, a study found.
Genes responsible for hair color come from both parents. Although the genes passed down from a child's parents determine hair color, variations can result in a child having a different hair color than both parents.
Y-linked traits are regulated by genes present on Y chromosome and are inherited from father to son as fathers pass the Y chromosome to sons. Thus, the correct answer is option D.
Physical traits such as eye colour and height may also be inherited, as well as behaviour patterns and health habits. Fathers have a significant impact on their daughters' lives and should strive to set positive examples for them.
Firstborns tend to possess psychological characteristics related to leadership, including responsibility, creativity, obedience and dominance. They are also more likely to have higher academic abilities and levels of intelligence than their younger siblings.
The pigment, melanin, passed on to your baby by you, determines skin tone. In the same way she inherits your hair colour, the amount and type of melanin passed on to your baby is determined by a number of genes (approximately six), with one copy of each inherited from her father and one from her mother.
