Answer:
Alleles that are rare in the ancestral population (Germany) become common in the new population by random chance.
Explanation:
The founder effect is the change in the allele frequencies of a population by a chance event when a small group of individuals migrate from the large original population and colonize a new region. The gene pool of the Amish population is quite different from the original population as the colonizing individuals did not carry all the alleles and genes present in the original population.
The founder effect results in the expression of harmful recessive alleles that were otherwise masked in the heterozygous genotype of the original large population. Small colonizing population exhibits increased homozygosity and reduced genetic variations leading to the expression of rare diseases that were masked by heterozygosity in the large parent population.
Answer:
Phases of mitosis has been shown in the diagram
Explanation:
Answer: enable them to imprint on the facility
Explanation:
The addition of the chemicals to the river will help the fishes to recognize that this was their native habitat where they got birth and grew. This will act as a imprint formed by the facility which will help the fishes to recognize the water of the facility. This will help in increasing the number of fishes which return back to the facility.
