Which parent determines the hair of the child?
Takeaway. Curly hair is determined by factors you inherit from your biological mother and your biological father. There's no single gene that determines the way that your hair looks. The way your hair looks when you're born is also a clue into the genetic information you'd pass to your own children if you have them.
What is the dominant gene for hair color?
For hair color, the theory goes: Each parent carries two alleles (gene variants) for hair color. Blonde hair is a recessive gene and brown hair is a dominant gene.
Can 2 brown haired parents have a blonde child?
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.
How is hair color determined genetically?
The type and amount of melanin in hair is determined by many genes, although little is known about most of them. The best-studied hair-color gene in humans is called MC1R. This gene provides instructions for making a protein called the melanocortin 1 receptor, which is involved in the pathway that produces melanin.
How can I predict my child’s hair 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.
What genes do fathers pass on?
Genetics of Inheritance While moms pass down an X chromosome to their children—since women have two x chromosomes—dads pass down either an X or Y chromosome. The presence of a Y chromosome determines whether your baby's a boy or a girl. Additionally, certain genetic traits are found exclusively on X or Y chromosomes.

What does a baby get from the father?
From their mother, a baby always receives the X-chromosome and from father either an X-chromosome (which means it will be a girl) or a Y-chromosome (which means it will be a boy). If a man has a lot of brothers in his family, he will have more sons and if he has a lot of sisters, he will have more daughters.

Our mitochondrial DNA accounts for a small portion of our total DNA. It contains just 37 of the 20,000 to 25,000 protein-coding genes in our body. But it is notably distinct from DNA in the nucleus. Unlike nuclear DNA, which comes from both parents, mitochondrial DNA comes only from the mother.
