Determine the difference in the phenotype of albinism among Hopi Native Americans and other types of albinism and the mutated gene resulting in those phenotypes.

The mutations found in the CF gene that result in cystic fibrosis are recessive because.. (Justify your answer)  a) CF is fatal and if the alleles that caused CF were dominant it would not be inheritedb) The CF mutations that occur result in no protein being produced and this is the only possible way for the mutations to be recessivec) Normal or near normal cellular function can occur from the protein produced by the normal allele in a carrierd) CF mutations only result in a protein that has normal function if there is also a normal CF protein in the cell

Many different alleles of a gene may exist in a population, yet each individual within the population does not carry more than two alleles of the gene. Is this true or false? A specific DNA mutation results in the production of a nonfunctional Chloride Ion Channel protein. The wildtype (normal) DNA sequence and the mutant DNA sequence that code for the Chloride Ion Channel protein, would they be considered different alleles of the same gene?

Suppose we define the Alzheimer’s disease phenotype as being diagnosed with the disease by age 75 years. In the human population, there are three alleles of the ApoE gene: ε2, ε3, ε4. They form an allelic series such that: 70% of 75 year olds with the ε4/ ε4 genotype have the Alzheimer’s phenotype 60% of 75 year olds with the ε3/ ε4 genotype have the Alzheimer’s phenotype 40% of 75 year olds with the ε3/ ε3 genotype have the Alzheimer’s phenotype 30% of 75 year olds with the ε2/ ε4 genotype have the Alzheimer’s phenotype 10% of 75 year olds with the ε2/ ε3 genotype have the Alzheimer’s phenotype If I have the ε4/ ε4 genotype and my wife has the ε2/ ε3 genotype, what is the probability that our child will have Alzheimer’s by age 75. Explain your reasoning
