What is the phenotype for curly hair?
A person with one copy of the straight hair allele and one copy of the curly hair allele will have wavy hair. If the only alleles for hair texture were straight and curly, there would be three phenotypes: straight, curly, and wavy.
Do you get curly hair from Mom or Dad?
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.
Can a child have straight hair if both parents have curly 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. This corresponds to saying that you have inherited both copies of the gene for curly hair from your parents.
How do you determine phenotype?
The term “phenotype” refers to the observable physical properties of an organism; these include the organism’s appearance, development, and behavior. An organism’s phenotype is determined by its genotype, which is the set of genes the organism carries, as well as by environmental influences upon these genes.
What causes curly hair?
Follicle Shape- The shape of your hair follicle largely determines your curl. Oval follicle shapes produce curly hair while round follicles produce straight hair. It’s this difference in shape—when one side is curved but the other side is flat—that makes your hair curl.
Will my kid have curly hair if I have curly hair?
A dominant gene masks or suppresses other traits from appearing. Where hair type is concerned, curly is a dominant trait. So if one parent passes on the curly-hair gene and the other a straight-hair gene, it’s more likely that their child will have some sort of curl pattern to their hair.
