, What behavioral genetic research finding seems to support the conclusion that the effect of growing up in the same home environment is rather minimal? a. The personality traits of adoptive siblings raised in the same family are correlated around .05. b. The personality traits of monozygotic (MZ) twins are correlated at .50 on average. c. The personality traits of dizygotic (DZ) twins are correlated at .30 on average. d. The personality traits of adoptive siblings raised in the same family are correlated above .25.

a. The personality traits of adoptive siblings raised in the same family are correlated around .05.

Explanation:

Both genes (inheritance) and environment play roles in literally everyone human traits including human personality. Nonetheless, recent research involving adoptive siblings and monozygotic twins, which are genetically identical, strongly suggest that there is a predominant genetic influence on this human trait. In consequence, environmental factors play minor roles in human behavior. In the case above indicated (i.e., adoptive siblings in the same home), the low correlation value shows a minor effect of the environment on the personality.

the denominator has a very specific role.

during the process of dna replication, brdu can replace thymidine and incorporate into the newly synthesized dna, cell proliferation thus can be reflected in the extent of brdu incorporation.
