what would be the relationship?

Question

if i had naturally curly hair and married some one with naturally straight hair then had kids with wavy hair. what would be the relationship between the alleles for hair texture?

A) wavy hair is dominate to both straight and curly
b) pleiotropy
c) straight hair and curly hair are sex linked but wavy isnt
d)codominance
e)incomplete dominance

Answer 1

Codominant is the correct answer.
A number of human traits are the result of 2 types of alleles that are equally dominant. Such traits are said to be codominant for that trait. When an individual is heterozygous for such traits, the resulting phenotype or expression of these two traits is a blending, because both traits are expressed equally. The alleles for curly hair and straight hair are examples of alleles for a trait that are codominant. Individuals with curly hair are homozygous for curly hair alleles. Individuals with straight hair are homozygous for straight hair alleles. Individuals who are heterozygous, with one of each allele have wavy hair, which is a blend of the expressions of the curly and straight hair alleles.

Answer 2

Incomplete dominance. Codominance would be if the hair was both straight and curly, not a blend of the two.

An example of codominance is people with type AB blood, because bothe the allele for A and the allele for B are being expressed.

An example of incomplete dominance is the snapdragon one above.

Best of luck! That confused me my first time through, too.

Answer 3

I believe the answer is incomplete dominance. I checked out my bio textbook just to be sure. The example it gives is of snapdragons. When a red and a white are bred together, the offspring are pink, which sounds basically similar to your example of hair.

Answer 4

curly hair character is dominant over straight hair character..

Answer 5

ur gene tries to make her's curly. so you end up with wavy at some parts and others straight

Answer 6

Your gene is dominant.
