Can you inherit curly hair from grandparents?

So back to your question, here is a simplified answer. If both of your parents have curly hair, you are more likely to inherit the trait of curly hair. Then the curly hair gene could have been passed down through generations and your parents are carrier of that gene, which manifested its trait in you!

Is curly hair dominant over straight hair?

Curly hair is considered a “dominant” gene trait. Straight hair is considered “recessive.” To put that in simple terms, that means that if one parent gives you two curly haired genes and the other parent gives you a pair of straight-haired genes, you’ll be born with curly hair.

Can curly hair parents straight hair child?

It is not possible for two ‘unmixed’ parents having straight-hair to reproduce an offspring with curly hair. This corresponds to saying that you have inherited both copies of the gene for curly hair from your parents. But, one parent could be having straight hair while the other, curly hair.

What kind of hair of the child when parents have a curly and straight hair?

If one parent has curly hair and the other has straight hair, each offspring will inherit one of each allele from parents. All offspring will have wavy hair.

What makes hair straight or curly?

It is the shape of the follicle which contributes to determining whether your hair is straight or curly. If the follicle is round, hair will tend to grow straight, while an oval follicle will give wavy hair and a hooked or elliptical-shaped follicle will give you curly hair.

Does curly hair skip a generation?

So, while curly-haired parents tend to have curly-haired kids, there’s no guarantee it will happen. Because many different genes are involved, even a curly-haired parent can have—and pass along—straight-hair gene variations.

What is my genotype If I have curly hair?

If you have curly hair, your genotype is two curly hair versions of the hair texture gene: one from mom and one from dad. An allele is the term geneticists use to refer to a version of a gene. The curly hair allele and the straight hair allele are just two of several alleles that help to determine your hair texture.

What are the alleles for Curly and straight hair?

If you have two curly alleles (CC) , you’ll have curly hair. If you have one curly allele and one straight allele (Cs), your hair will be wavy. Finally, two straight alleles ( ss) will give you straight hair. A wavy-haired person can contribute either a C or an s gene.

Can two curly headed parents have a straight haired child?

One way for the couple you describe to have a straight haired child is if the curly headed parent actually has wavy instead of curly hair. It may seem like a minor distinction but from a genetic point of view, the difference is critical. Why would this distinction matter?

Is curly hair dominant or recessive?

Effect of genes on hair. As mentioned earlier, curly hair is an autosomal dominant trait, which means that one of the parents has straight (normal) hair, while the other has curly hair. So, you get genes of both types, but the dominant curly hair gene trumps the straight hair gene and expresses itself in the offspring, i.e., yourself.
