Is it possible for 2 curly haired parents can have a child with straight hair?
It is not possible for two ‘unmixed’ parents having straight-hair to reproduce an offspring with curly hair. If both parents have curly hair, it is more likely to inherit that trait of curly hair.
Can you have both curly and straight hair?
Yes your hair can be curly and straight at the same time. It’s completely normal to have a mix of curl patterns on the same head. Your curls can and probably will change over time.
Is straight and curly hair genetic?
As already mentioned, curly hair is an autosomal dominant trait, which means that one of the parents has straight 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, that is, in yourself.
Is straight hair or curly hair dominant?
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.
Is it possible for two parents that have straight hair to?
If only one parent was Cc, and the other was cc, the chances would chance to a 2/4 of straight hair, and a 2/4 chance of wavy hair. No, it is not possible for two “purebred” straight-haired parents to produce a curly-haired child.
What happens if both parents have curly hair?
If both parents have curly hair, then your baby will most probably end up with curly hair. However, even if the parents do not have curly hair, the baby might get the traits from another ancestor that had it. The dominance of the curly hair genes can carry over generations.
Can a straight gene cause a child to have curly hair?
Yeah…sort of. In an incomplete dominance scenario, the genes will blend, so the child will have curly hair, but it will be less curly than the mother’s because of the straight gene from the father. Here’s another one.
Can a baby have straight or curly hair?
If one of the parents has curly hair and the other has straight hair, that curly hair gene will most likely dominate the other gene. So the baby will end up with either curly or wavy hair. If both parents have curly hair, then your baby will most probably end up with curly hair.
Why do two people with straight hair have a child?
If two people with straight hair have a child, then they’ll usually have straight-haired kids. This is because the parents will have mostly S’s to give. Same thing with curly hair (except of course the parents with curly hair would have curly haired kids because they mostly have C’s to give).
Why do some parents have a curly hair child?
This is because the parents will have mostly S’s to give. Same thing with curly hair (except of course the parents with curly hair would have curly haired kids because they mostly have C’s to give). I’ve shown an example of two curly haired parents having a curly haired child on the right.
How are curly hair and straight hair inherited?
But many genes are more complex in how they are transmitted. In the past, geneticists believed that curly hair was a dominant gene and straight hair a recessive one. Now they are saying that hair texture is inherited through a more complex mingling of genes, called incomplete dominance.
Do you have straight hair and curly hair?
People with straight hair had two copies of the straight version, people with curly hair had two curly versions and people with wavy hair had one of each. So your case would be pretty easy to explain. You and your husband have one straight and one curly version of the gene which explains your wavy hair.
