Twin studies are often used in the research of human behavioral traits. Although helpful, there are limitations to these studies. All of the following are limitations to twin studies EXCEPT: Traits are assumed to be simple Mendelian inheritance, discounting additive alleles and epistasis Dizygotic twins will often share more than 50% of their genes Monozygotic twins are often treated more similarity than dizygotic twins O Twins studies are a mechanism to understand the genetic and environmental components of a trait Twins reared apart are often adopted out to families of similar income, ethnicity, and religion

The amount of expression within individuals varies O The disorder is present in 20% of the individuals that have the dominant allele 20% of the individuals who have the dominant allele may have genes that mitigate (prevent) the disorder and therefore do not display symptoms O The trait is present in 80% of the total population.

Which of the following statements about Mendelian or complex disease is TRUE? O Mapping of quantitative trait loci does relies on genetic variations that directly contribute to the trait of interest. O Genetic methods for studying Mendelian phenotypes, such as crossing, is not useful for mapping quantitative trait loci. Genetic factors determine Mendelian traits, while environmental factors determine complex traits. O Both Mendelian and complex traits are associated with single gene locus. Genome-wide association studies rely on polymorphic markers that are in linkage disequilibrium with alleles that contribute to the trait of interest.

. Autism is a neurological disorder thought to becaused by mutant alleles of one or more genes.Scientists had been wondering why the number ofchildren diagnosed as autistic increased dramaticallyin a decade, from 1 in 500 in 2002 to 1 in 88 in 2012.Researchers now think that they might have found atleast part of the answer: Men are fathering children atlater and later ages. A paper published in the journalNature in 2012 showed a correlation between paternalage and the incidence of autism; the age of the motherwas not a factor. How does this observation provide apossible explanation for the apparent increase in therate of autism?
