Can two light skinned parents have a dark baby?
The short answer is, yes! A couple can have a baby with a skin color that isn't between their own. The long answer, though, is much more interesting. The long answer has to do with the parts of your DNA that give specific instructions for one small part of you.
Both parents may be dark but if there is a fair skinned blood relative even distant or even existing 2 or more generations before, the baby can be fair. Rarely will there be genetic mutation causing change in physical characteristics.
His physical features come from the dominant genes of both his parents. This combination will ultimately determine the baby's skin color. This is one of the charming parts of having children! They are their unique person, for us as parents to love and support just the way they are!
Dear Ken, It is not uncommon for two dark skinned persons to have a light skinned baby. Skin colour is a physical characteristic that is determined by genes inherited from one’s parents. However, the actual colour depends on which gene is more dominant.
It is indeed possible that you can have a baby with darker skin than the parents, especially if close family members have very dark skins.
In the US in 1998, a white woman gave birth to one white and one black baby in what became known as the “scrambled eggs” case. After a “bitter custody battle” the black couple whose embryo was mistakenly implanted into the white woman won custody of the black baby.
Inheritance of Skin Color
Each gene has two forms: dark skin allele (A, B, and C) and light skin allele (a, b, and c). Neither allele is completely dominant to the other, and heterozygotes exhibit an intermediate phenotype (incomplete dominance).
Genes from your father are more dominant than those inherited from your mother, new research has shown.
The genetic mechanism behind human skin color is mainly regulated by the enzyme tyrosinase, which creates the color of the skin, eyes, and hair shades. Differences in skin color are also attributed to differences in size and distribution of melanosomes in the skin. Melanocytes produce two types of melanin.
Differences in skin and hair color are principally genetically determined and are due to variation in the amount, type, and packaging of melanin polymers produced by melanocytes secreted into keratinocytes. Pigmentary phenotype is genetically complex and at a physiological level complicated.
At what age do babies get their permanent skin color?
Baby's skin color may change
(In fact, some babies can take up to six months to develop their permanent skin tone.) This is perfectly normal, but do keep an eye out for a yellow cast to the skin, which could be a sign of jaundice.
This is due to the fact that the blood circulation is still picking up speed. So, no matter what your country of origin is, your baby is going to be slightly darker in complexion and THIS SHOULD BE THE LEAST CAUSE OF WORRY.
Willimina and Valentina aren't step siblings, half sisters, or adopted. These beautiful little girls are biological siblings who happen to have different skin tones, but to Willimina, the only difference between them is baby Valentina's chubby cheeks.

Research from 2017 found that babies' skin changed significantly as they aged. Researchers noted that babies' skin became lighter and less red between 2–20 months old. Additionally, babies' skin was found to increase in yellow pigment until they reached 20 months old.
The skin can adapt melanin production to sunlight exposure. So if your baby is exposed to sunlight regularly, his skin will get darker, and if he hardly gets any direct sunlight for long, he might appear fairer. But he will never get fairer than his natural skin colour, which sets in soon after birth.
African American and biracial infants may have sensitive skin that's prone to dryness and dark spots (hyperpigmentation). At birth, your child's skin is likely to be a shade or two lighter than her eventual skin color. The skin will darken and reach its natural color in the first two to three weeks.
The ovary is connected to her uterus through the fallopian tube. The egg stays within this tube where it can meet the sperm of her husband after sexual intercourse. But the egg stays here just for twelve to twenty-two hours. It gets fertilized, an embryo results that grows into a fetus inside the uterus or womb.
A new study by Missouri School of Journalism researcher Cynthia Frisby found that people perceive a light brown skin tone to be more physically attractive than a pale or dark skin tone.
Color and cancer
These early humans probably had pale skin, much like humans' closest living relative, the chimpanzee, which is white under its fur. Around 1.2 million to 1.8 million years ago, early hom*o sapiens evolved dark skin.
Which eye color is dominant?
Eye color was traditionally described as a single gene trait, with brown eyes being dominant over blue eyes. Today, scientists have discovered that at least eight genes influence the final color of eyes. The genes control the amount of melanin inside specialized cells of the iris.
The genetics of height
If they are tall or short, then your own height is said to end up somewhere based on the average heights between your two parents. Genes aren't the sole predictor of a person's height. In some instances, a child might be much taller than their parents and other relatives.
What determines a baby's eye color? In general, children inherit their eye color from their parents, a combination of the eye colors of Mom and Dad. A baby's eye color is determined by the parents' eye color and whether the parents' genes are dominant genes or recessive genes.
Sons can only inherit a Y chromosome from dad, which means all traits that are only found on the Y chromosome come from dad, not mom. Background: All men inherit a Y chromosome from their father, and all fathers pass down a Y chromosome to their sons. Because of this, Y-linked traits follow a clear paternal lineage.
Tishkoff reasoned that powerful genetic variants must be responsible. Studying 1,570 people in Ethiopia, Tanzania and Botswana, she and her colleagues discovered a set of genetic variants that account for 29 percent of the variation in skin color. (The remaining variation seems tied to genes yet to be discovered.)
The genetic mechanism behind human skin color is mainly regulated by the enzyme tyrosinase, which creates the color of the skin, eyes, and hair shades. Differences in skin color are also attributed to differences in size and distribution of melanosomes in the skin. Melanocytes produce two types of melanin.
Here, even though the child has the same number of black and red cards as either parent, the child is much, much lighter than either parent because of those two queens of hearts. This may seem like a silly rule, but it's actually how some genes work. In fact, it's what happens for people with light skin and red hair.
