Why does a person who inherits an allele for curly hair and an allele for straight hair have curly hair?

This happens because of the dominant and recessive alleles. This means that if your dad had curly hair naturally, and your mother had straight hair you would have both alleles, but your mum's gene of the straight hair was recessive. It was dominated by the curly hair gene. Bullied away, if you prefer. It is totally normal, and often happens. However, that does not mean the curly hair gene always is dominant, it just means that your curly hair gene was. If you would prefer straight hair though, you can buy straighteners, and hair straightening products.

Wavy hair is caused by the shared expression of a allele for curly hair and an allele for straight hair?
it depends on which allele is most dominant in the parents.
If straight hair is genetic why do you have straight if none f your ancestors did?
it is because the parents each were heterozyous dominant. meaning each of them had a dominant allele and a recessive allele. the dominant allele would be the curly hair, and the recessive allele would be the straight hair. There would be a 1/4 chance that the child would have curly hair, and a 3/4 chance that they would have curly hair. Say that the Curly hair allele was H and the straight hair allele was h. In order for the parents to have curly hair, they would either have to have an HH gamete or an Hh gamete. Seeing as though the child came out with curley hair, both parents would have to have an Hh gamete. In order to find out the probability, you multiply the parents gametes. (Hh)(Hh). This will give you HH, Hh, Hh, hh. seeing has three of the gametes have the dominant allele, this child will have curly hair, and one is a homozygous recessive, so it will turn out with straight hair.
Why might one person have curly hair and another have straight hair?
Hair is determined by genetics, which causes one person's hair to be curly and another's hair to be straight.
Which looks better straight or curly?
It depends on the person... Straight hair is cool, swaggish, and fun. Curly hair is hmmm..... I like straight better haha

I'd suppose it varies from person to person

Why might a person have curly hair or straight?
usualy if a childs mother or father has curly hair they to would probaby have curly hair to because it is a genetic thing
Can a person with Straight Hair get Curly Hair?
With a curling iron or with a perm, yes.
Do more people have curly hair or straight hair?
It is actually more common for people to have not straight or curly hair, but wavy hair. Like skin color, hair type is a trait that tends to "mix". If a person with white skin and a person with black skin have an offspring, they will have a light brown skinned offspring. If a person with curly hair mates with a straight haired person, there is a chance they will have wavy hair
How are dominant and recessive traits represented?
Autosomal recessive alleles ( both males and females) and X-linked alleles in females always express themselves in homozygous condition. On other hand, X -chromosome linked recessive allele express singly in males.
