“Ancestry tests” are sold by many companies. There are significant limitations to these tests. Why is this the case?

“Ancestry tests” are sold by many companies. There are significant

limitations to these tests. Why is this the case?

-High genetic variation among individuals within most populations makes it difficult to identify specific sequences that can reliably indicate membership in a population.
-Evaluating too few genetic loci, of which just a small number happen to be similar, can lead to the conclusion that individuals are much more genetically similar than they actually are.
-A DNA match between two individuals living today is not a match with an ancestor. Rather, it suggests that the two people may have inherited the DNA sequence from a common ancestor.
-High rates of gene flow between populations reduce the reliability with which any sequence can demonstrate membership in one particular population.
-all of these are limitations to “Ancestry tests”

For which of the following is there clear evidence that a single gene mutation is the cause of the associated disorder?

-A mutation in the FOXP2 gene causes speech disorders
-A mutation in the gene that encodes Happy Hour causes alcoholism
-A mutation in the MAOA gene causes aggression
-A mutation in the HD gene causes Huntington Disorder
-A mutation in the Complement Component 4 gene causes Schizophrenia

What is the function of a normal MAOA protein?

-It is a neurotransmitter
-It is an enzyme responsible for the construction of neurotransmitter receptors
-It is an enzyme essential in the formation of certain neurotransmitters
-It carries neurotransmitters across synapses
-It breaks down neurotransmitters and clears them from the synaptic cleft
