Biological siblings (reared in the same home) will be moderately correlated for behavioral phenotypes such as number of hours watching tv per day. This is because the pair shared both additive genetic influences (i. e., genetic propensity towards general activity level, boredom, lethargy, etc.) and shared environmental influences (i. e., parental modeling of high or low tv watching, access to streaming services, number of accessible tvs in household, etc.) that contributes to pair similarity. List the sources of resemblance that may lead to a correlation in tv watching across the following types of family pairs: a. birth parent with their biological child (reared in the same home)
b. adoptive Siblings (reared in same home)
c. biological siblings adopted into different homes
d. adoptive parent With adoptee child (reared in the same home)

The options related to your question is not available hence I gave a general and correct answer based on what will influence each type of family pairs listed below

answer :

A) Birth parent with their biological child ( reared in the same home ) : The sources of resemblance are Both additive genetic influences and shared environmental influences.

B) Adoptive siblings ( reared in same home ) :The source of resemblance is  shared environmental influence

C) Biological siblings adopted into different homes : The source of resemblance is additive genetic influences

D) Adoptive parent with adoptee child ( reared in the same home ) : The source of resemblance is shared environmental influences

Explanation:

The sources of resemblance that may lead to a correlation in tv watching across the various types of family pairs are listed below

A) Birth parent with their biological child ( reared in the same home ) : The sources of resemblance are Both additive genetic influences and shared environmental influences.

B) Adoptive siblings ( reared in same home ) :The source of resemblance is  shared environmental influence

C) Biological siblings adopted into different homes : The source of resemblance is additive genetic influences

D) Adoptive parent with adoptee child ( reared in the same home ) : The source of resemblance is shared environmental influences

the correct answer is b
