Allele frequency is used to display the genetic diversity of a species population .
Explanation:
To calculate the frequency of the recessive allele we use the
THardy-Weinberg equation
p² + 2pq + q²
p+q=1
p is the frequency of the homozygous dominant genotype
q is the frequency of the homozygous recessive genotype
2pq is the frequency of the heterozygous genotype.
Total number of individuals = 45 + 30+ 25 = 100
So, the frequency of recessive trait = 25/100 =0.25.
Thus, the value of q² = 0.25
So, q would be equal to square root of 0.25 which comes out to be 0.5
Answer:
Stevie has an oral fixation.
Explanation:
<em>Oral fixation</em> occurs in the oral stage of development and is characterized by obsessive mouth stimulation. The most commonly suggested trigger for this type of fixation is when a child has a<em> problem during the weaning stage;</em> either being weaned too early or too late. Later in life, such a child may develop an obsession with activities that involve the mouth such as <em>over-eating which leads up to being overweight, talking excessively, excessive drinking and in some cases a smoking addiction.</em>
