Is it true that curly hair is an alelle defect, with the only effect being the curly hair?

Answer 1

It isn't a defect, it's a codominant genetic trait, which means that the genes for curly and straight hair are equally dominant and if you have one of each, you will have wavy hair.

I don't believe that there is any evidence to link it with any other genetic trait, good or bad.

Answer 2

It's wrong to call it a defect it's merely an allele, an alternative form of genotype present. Even if it's reccessive, it's not neccesary defect. By the way 5-fingered allele is reccessive. And yes the phenotype expressed would only be curly hair which os so because of the defined gene loci unless of course that loci could be controlling multiple expression or the phenotype dependent of a variety of genes

Answer 3

no it is not true that it is a defect - it is only a variation between straight hair which is oval in shape (in cross section) due to the arrangement of the amino acids that make up keratin; and curly hair which is circular in shape due to a different arrangement. Thus if one parent has straight hair, say for example Chinese hair; and the other parent has very curly hair, perhaps African hair, then the children may have straight, very curly or any combination from wavy to loose curls.

Answer 4

Curly hair is not a defect. It is a Mendalian dominate gene
that is expressed either homozygously or heterozygously

Answer 5

Not a defect, a variation.
I doubt anyone could be sure that the effected gene effects nothing else.

Answer 6

Well how come that, having poker straight hair for my first 35 years, the instant I got pregnant, my hair went all curly? Can you explain that?

Answer 7

It comes from using a curling tong !

Answer 8

What the bleeding hell is "alelle"?

Answer 9

its something to do with the jeans i would have thought

Answer 10

naa its from curl activator
