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
Answer:
True, the model had to change as new information came to light.
After the invention of new instruments, it enable us to do more research and verify old theories.
Dalton atomic theory states that matter is composed of very small particles called atoms which is indivisible. Indivisible means cannot be broken down into simpler substances. But Rutherford performed an experiment and concluded that atom is divisible into proton, electron and neutron. Electron is present in the shell while proton and neutron are present inside the nucleus of an atom.
Answer:
True
Explanation:
The dominant allele increases in frequency as it masks recessive alleles.That is why a dominant trait/allele will become something is more commonly passed down to offspring
