Also called Birth rate. It is the member of children born per 1000 living persons per year.
<span>If 25 percent of a breeder’s guinea pigs has long hair, the frequency of the recessive allele (q) is 50%. Let A be dominant allele and a be recessive allele. The frequencies are as following: p - the frequency of dominant allele, q - the frequency of recessive allele, p^2 - the frequency of genotype AA (short hair), 2pq - the frequency of genotype Aa (short hair), and q^2 - the frequency of genotype aa (long hair). So, we know that q^2 = 25% = 0.25. We need to find q. q = √q^2 = √0.25 = 0.50 = 50%.</span>
The teacher most likely asked for additional trials because it was necessary to see data from more plants before the conclusion could be accepted.
Explanation:
- Any experiment should have multiple trials given so that accuracy of the result could be obtained.
- Repeating same experiments tests the consistency of a particular result and makes sure that the results will not be effected by random events occurring within the system or surrounding.
- Thus the conclusion becomes more precise and accurate.
