The most important reason to control the conditions of an experiment is to make sure that the environment is affecting the results of the experiment--which would void the study.

It is very important to control the conditions of an experiment because FAILURE TO DO THIS WILL MAKE THE RESULTS OF THE EXPERIMENT INVALID.

A controlled experiment refers to an experiment that is conducted under controlled conditions. Conducting experiments under controlled conditions helps scientists to minimize the changes in all other variables with the exception of the ones been tested.

3. In one population, 18 individuals have long hair and 182 individuals have short hair. It is known thatmating has been random
pishuonlain [190]

Answer: p (short hair) = 0.91 and q (long hair) = 0.09

Explanation: In the population, short hair is a feature of domnant allele, because there are more short haired individuals than with long hair. In genetics, p is the frequency for dominant allele and q is for recessive allele.

For this question, short hair is allele L and long hair is allele l

So, the frequency of short hair is p and of long hair is q.

To calculate the frequencies:

Frequency of allele L = (number of copies of allele L in population) / (total number of L/l gene copies in population)

p = 182/200 = 0.91

The same formula goes for the recessive allele, so:

q = 18/200 = 0.09

Thus, the frequencies of hair allele are 0.91 and 0.09 for short and long, respectively.
