Is Curly Hair A Dominant Trait

What is the type of inheritance.

Is curly hair a dominant trait. We got two different traits. 1 if a person carries one allele for curly hair and another for straight hair this person will have curly hair. Of course it s always the dominant traits are always fairly randomized between parents.

To simplify things we can assume that curly and dark colored hair are dominant traits with single genes that control them. People sometimes suffer from an autosomal dominant disorder which means that they run a 50 chance of having a child with a mutated and dominant gene. Even if you have the curly haired.

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. Curly hair is an autosomal dominant trait.

If you have curly hair your genotype is two curly hair versions of the hair texture gene. A phenotype is your version of a trait. A genotype is your combination of genes that produce your phenotype.

This means two things. Trait a color. Parents with curly hair tend to have children with curly hair.

The term dominant means that a gene will either mask or suppress other traits from appearing. A curly. Curly hair traits are straightforward if rather tedious to measure given that hair is easily sampled and good methods to quantify curl have been developed.
