Wavy hair is a very easy example that this is false.  It's a merge between straight and curly hair.  Our traits tend to mix and blend together, it's not so simple.  Everybody isn't just tall or short, one or the other.  Everybody is a different height because it's a mid between your parents.

Whitepunk [10]

Answer:

INTERNEUTRONS

Explanation:

INTERNEUTRONS

Interneutrons are really the highest number of neurons and spinal cord. They are accountable for the diverse communication system of the nervous system and try and resolve between inputs and outputs.

Interneurons are groups of nerve cells commonly found in nervous system integrative areas where axons & dendrites are restricted to a specific area of  brain.

Genrish500 [490]

The question is incomplete. Here is the complete question.

You are studying a population of ground squirrels. You trap 100 individuals and find 9 that have a light colored coat and the rest have a dark coat. You know that light coat color is recessive in ground squirrels. What is the allele frequency for the light coat allele  and the dark coat allele? How many of the dark coated individuals do you expect to be heterozygotes at the coat color gene? Assume the population is at H-W equilibrium.

Answer: Allele frequency for light coat: q = 0.3;

              Allele frequency for dark coat: p = 0.7;

             There will be 42 heterozygote;

Explanation: A population in H-W equilibrium is a population which doesn't change from one generation to the next if there are no disturbing factors, as migration or mutation.

It follows the equation: p^{2}+2pq+q^{2}=1.

p represents the frequency of the dominant allele;

q represents the frequency of the recessive allele;

2pq represents heterozygote individuals;

The sum of frequencies of both alleles must be 1, i.e.: p+q=1

For the population of squirrels:

  • Frequency of recessive allele

q^{2} = \frac{9}{100}

q = \sqrt{\frac{9}{100}}

q = 0.3

  • Frequency of dominant allele

p+q=1

p=1-q

p=1-0.3

p = 0.7

  • Frequency of heterozygote

2pq = 2*0.7*0.3 = 0.42

In a population of 100 individuals: 0.42*100 = 42

The allele frequency for the light coat is 0.3; for the dark coat is 0.7.

It is expected to have 42 heterozygote individuals in this population.
