Answer:
Various brands of nail polish utilized by Sarah.
Explanation:
In conducting an experiment, two variables are assessed; these are the independent variable and the dependent variable. The variable that is altered consistently to observe its effects is identified as independent variable while the one under examination is termed the dependent variable.
In this scenario, Sarah aims to determine which nail polish brand lasts longest without chipping. Thus, the diverse brands of nail polish she experiments with are designated as the independent variable.
Utilize the Hardy Weinburg equation pertaining to allelic frequency.
P2+2pq+q2=1
Calculating gives us 174/1378 = 0.126 = q2
Consequently, q2 equals 0.126, which means q = 0.355.
<pGiven that q = 0.355 and noting that p + q = 1, therefore
P = 1 – 0.355 = 0.645.
To determine the population of homozygous dominant (p2);
(0.645)2 x 1378 = 0.416 x 1378 = 573.
For the heterozygous population (2pq);
(2 x 0.645 x 0.355) x 1378 = 0.458 x 1378 = 631.
The number of recessive individuals (q2) equals 174.
