Answer:
reduced; were not
Explanation:
According to a study conducted by Honts, Raskin, and Kircher (1994), the use of countermeasures reduced the detection of guilty suspects by 50%, and the examiners were not able to tell that the suspects were manipulating their own arousal patterns. This was a findings from their research titled "Mental and Physical Countermeasures Reduce the Accuracy of Polygraph Tests".
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
