In a brunette-brunette pairing, your offspring will likely have a shade of brown. In a black-brunette pairing, the child will likely have black hair, but could end up with a shade of brown.
Unless you're of European ancestry, you don't have much of a chance of inheriting this rare hue. If both parents are brunette, they can only have a blonde child if they both carry the recessive blonde trait. A regulatory molecule sends a signal that triggers a hair follicle to create hair in a certain color.
Who the child "gets it from" really depends on the parents' hair color and a bit of chance. For example, if one parent has dark brown hair, and the other has light brown hair, the baby will most likely get their hair color from the parent with darker hair.
Black hair are dominant over brown hair.
Blonde hair is a recessive gene so both parents just need to have blonde hair somewhere in their ancestory for the child to have a chance at being blonde. Both parents can have dark hair for several generations but if they ever had a blonde ancestor they carry the gene for it.
The Truth About Dominant and Recessive Genes
Each parent carries two alleles (gene variants) for hair color. Blonde hair is a recessive gene and brown hair is a dominant gene.
It turns out that brown hair is dominant. That means that even if only one of your two alleles is for brown hair, your hair will be brown. The blond allele is recessive, and gets covered up. If two brunette parents have a blond child, they had to have instructions for making blond hair hidden in their DNA.
One popular myth is that hair loss in men is passed down from the mother's side of the family while hair loss in women is passed down from the father's side; however, the truth is that the genes for hair loss and hair loss itself are actually passed down from both sides of the family.
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.

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.
Do grandparents' eye color affect baby? Yes! Grandparents' eye color can also impact baby's eye color. Baby eye color is genetic, and genes pass from generation to generation.
Since you need two pieces of “red hair” DNA to have red hair, your child will only have red hair if they receive “red hair” DNA from both parents. Even if you don't have red hair, you can still pass on a red hair allele to your child!
The rarest natural hair colour is red, which makes up only one to two percent of the global population. You commonly see these hair colours in western and northern areas of Europe, especially Scotland and Ireland. However, natural redheads may not exist for much longer.
If neither parent is a redhead but both carry the gene, there is a 25% chance their child will have red hair and a 75% chance their child will carry the gene themselves. So, that's how two dark-haired parents can end up with a redhead baby. It's only a 1 in 4 odd but it does happen more often than you would think.
Flexi Says: Two brown-eyed parents (if both are heterozygous) can have a blue-eyed baby. If both the parents have brown eyes, then there is generally a 25% chance for their child to have blue eyes. Because both the brown-eyed parents have a recessive blue-eye gene and can pass it to the next generation.
All men inherit a Y chromosome from their father, which means all traits that are only found on the Y chromosome come from dad, not mom. The Supporting Evidence: Y-linked traits follow a clear paternal lineage.
Green is considered by some to be the actual rarest eye color in the world, though others would say it's been dethroned by red, violet, and grey eyes. Green eyes don't possess a lot of melanin, which creates a Rayleigh scattering effect: Light gets reflected and scattered by the eyes instead of absorbed by pigment.
Unlike nuclear DNA, which comes from both parents, mitochondrial DNA comes only from the mother.
Physical features. Physical features such as hair color, hair texture, hairline, skin, and varicose veins are inherited from your mother.
A brown and blonde hair color is a fusion of any brunette and blonde hues to produce a natural, sun-kissed look. The resulting contrast between the dark and light pieces sets off a beautiful dimension for the hair!
Hair color is determined by the amount of a pigment called melanin in hair. An abundance of one type of melanin, called eumelanin, gives people black or brown hair. An abundance of another pigment, called pheomelanin, gives people red hair.
We know that brown hair genes dominate over blonde, red and other hair colours. This means that blonde or red hair is only possible by having two matching recessive genes.
