A certain trait is present in 30% of the population but the cause of this trait is still unclear. You perform an experiment where you get 100 sets of identical twins as volunteers in which one or both twins have the studied trait. Using what you know about twin studies, tell me what you would predict your findings to be if: a) the trait is entirely genetic in cause b) the trait is entirely environmental in cause c) the trait being studied is a complex trait

Step 1
This is because identical twins share 100% of their genes, while fraternal twins share only 50% on average. Therefore, if the trait is entirely genetic, we would expect a higher concordance rate in identical twins. Show more…

Twins are concordant for a trait when __. Select one: a. both twins share the trait with at least one parent b. only identical twins have the trait c. only fraternal twins have the trait d. all of the twins' siblings have the trait e. both twins have the trait of human diseases. A trait with a heritability value of 0.75 indicates that 75% of the phenotypic variability seen in the population is caused by ___ of the population. Select one: a. genetic differences b. environmental differences c. concordance d. epigenetic effects

If a trait varies greatly within a pair of identical twins, what is the most likely cause? A. Genetics B. Environment C. Nutrition D. Inherited True or False: Genetics and environment are both responsible for making you who you are. A. True B. False
Adi S.
Why do researchers find the study of fraternal twins important? a. They share similar environments and the same genetic code. b. Data collected concerning their similarities is necessary for calculating heritability. c. They are the same age and are usually raised in similar environments, but they do not have the same genetic code d. Results allow us to determine exactly how disorders ranging from heart disease to schizophrenia are inherited. e. They are typically raised in less similar environments than non twin siblings.
