Why are twin studies valuable in behavioral genetics research??

http://answers.yahoo.com/question/index?qid=20081020151205AAoU9K3

if both twins have the same types of behavior it could be because of genetics.if they studied only one person with lets say a very organized person.they cant possibly know if its ibc of there genes, but two people with same genes have that …

Why twin studies and adoption studies are used to understand gene…?

http://answers.yahoo.com/question/index?qid=20080923191429AAYlL6K

Identical twins have the same genetic material, so the study of monozygotic (identical) twins that were reared apart (ie separate families) provides insight into the impact of the environment for differences, and the impact of “nature”…

How is the twin method used to study genetic influences??

By looking at identical twins (ie 100% same genetically) who have been separated and raised in different environments researchers can determine the effect of genes vs environment.

Q: 1.summerize the evidence that led to the cromosome therory of heredity2.what patterns of inheritance do not follow mendel’s laws3.why are twin studies performed in genetics

A: 1) Mendel studied pea plants. He cross bred different colored and different shaped pea plants. This initially resulted in all dominant phenotypes being present in the first generation of offspring, and then hybrids in the second generation.2) Genes that are not linked to each other will not follow Mendel’s Law, but instead will follow the Law of Independent Assortment. If the gene for the size of a person’s skull and the gene for the size of a person’s liver are not on the same locus, they will express no relationship to each other in a species. (I think that is the answer)3) Scientists like to compare organisms with similar chromosomes and genes in order to view how much of an impacts genes actually have on an organism; they want to view how similar organisms with similar genes will react and be affected by the tests performed on them.
