Other things can depend. If the object is to fast or to slow, that could also delay reaction times.
Explanation:
Answer:
Two European men and two Polynesian women settled on a previously uninhabited tropical island. All four of the settlers have brown eyes, a dominant trait, but one of the Europeans is heterozygous and carries the recessive gene for blue eyes. No new settlers arrive,and nobody leaves the island.After a few generations,the percentage of blue-eyed individuals increases from the original zero to 25 percent.This is probably due to which of the following factors?
genetic drift
Explanation:
Genetic drift entails when there are changes in the gene frequency which occur in a gene that is existing. From the analogy above, it is a known fact that only gneetic drift could allow such to happen as mutation will only occur with a sudden change of gene which is not the case described above
In order to solve this problem we use these formula:
<span>p2 + 2pq + q2 = 1p + q = 1p = % dominant allele in the population
q = % recessive allele in the population
p2 = % homozygous dominant individuals
q2 = % homozygous recessive individuals
2pq = % heterozygous individualsFrom the given, we haveq2 = 21%Simply taking the square root,q = 4.58%</span>
Answer : B is the heaviest puppy amongst all.
Explanation : There are three comparisons shown in the figure, out of which B is assumed to be heaviest amongst all on the basis of following assumptions.
When weighing A and C puppy, A was found to have lighter weight than C. So, in this case C is the heavier puppy.
In second case, when C and D are weighed, both are found to be equal in weight.
Then last comparison was with B and D puppies where, D was observed to be of light weight and B proved to be the heaviest.
Therefore, the conclusion is that B is the heaviest puppy in comparison with rest others.
