The Afrikaners are an example of a founder effect that occurs when population and the random decrease in genetic variation is an example of genetic drift.
Explanation:
When some individuals from a population move to form a new colony, this phenomenon is called founder effect as in case of Afrikaners. The small population or group of individuals forming a new colony may not exhibit the full genetic diversity of the population they were once the part.
The alleles would get expressed in different frequencies than it would have in original population.
There are chances that some alleles are lost or missing also. The new colony formed has small population so chances of genetic drift are very strong.
Genetic drift does not depend upon the benefit or harmful effect of the alleles as it occurs merely by chance sampling. The small population of Afrikaners felt the effect of genetic variation hence strong genetic drift is seen in them.

Answer:
The difference in their structure gives them different properties and functions
Explanation:
If you're reading the 01.02A Chemistry of Life (Honors) course, go to the section called "Carbohydrates" Then go to the very last part of the section there you will find a sentence that says " They are all polymers made up of hundreds to thousands of glucose molecules bonded together, but the difference in their structures gives them different properties and functions." That's the sentence that I used to respond to this question.
True is the correct answer to your answer.
Crossing over happens in prophase I when the homologous chromosomes are sy naps ed. The two inner chromoatids exchanges sections with each other. This means that after the exchange the inner two chromatids have new combinations of alleles than their parents had. The two outer chromatids still have the parental combinations.So there are more kinds of chromatids ready to go into the gametes than there were before. This is an increase in variation.
