The amish are an example of a population where the founder effect has resulted in generally rare genetic traits being more commonly expressed.
(a) true
(b) false

false

Explanation:The issue of the Amish population is not genetically but more of a pychological and social constructed ideas that shape a particular group of people who follow those ideas.

This is passed down generation to generation through social practice rather than genetic traits.

People are not real born that way but they convert to those practices either due to the influence of their parents or because they choose to follow such practices .

The answer is TRUE.

Explanation:

The “Founder effect” phenomenon is a special case of genetic drift, where a new population originates from a few founder individuals, coming from a bigger population. This small population might or might not be genetically representative of the original one. Some rare alleles might be in exceed or might be completely lost. Consequently, when the small population increases in size, it will have a genetically different composition from the original one. In these situations, genetic variability is reduced and there exists the possibility of developing a peculiar allelic composition. This is the case of the Ellis syndrome characteristic of the Amish people from Pennsylvania, where there is a recessive allele frequency without precedent which, in homozygosis state, causes dwarfism and polydactyly. About 13% of the group members are carriers of the rare allele. The complete colony, isolated from the rest of the world, originates from a few individuals, and by chance, one of the originators was the first allele carrier.  

explanation:

the sequence of amino acids in a protein determines its function. the dna sequence of a gene determines the amino acid sequence of the resulting protein. thus, any changes in dna sequence can result in changes in protein function. this is called a mutation.
