DNA contains the instructions needed for an organism to develop, survive and reproduce. To carry out these functions, DNA sequences must be converted into messages that can be used to produce proteins, which are the complex molecules that do most of the work in our bodies.
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:
Erythrocytes, or red blood cells, are by far the predominant cell type in the blood smear. They appear as biconcave discs of uniform shape and size (7.2 microns) that lack organelles and granules. Red blood cells have a characteristic pink appearance due to their high content of haemoglobin.
