Answer:

The correct answer is:

It's necessary to collect DNA from male siblings, fathers, or paternal grandfathers

Explanation:

This happens because a parent gives half their DNA to their child. This means that when 10 STRs are studied, at least 10 bands will be identical on a gel comparing one parent and child. The Y chromosomal DNA is passed on from father to son, so it represents a nearly unbroken chain that moves through all recorded history.

kirill115 [55]

Answer:

Content validity

Explanation:

Content validity refers to the fact that a study actually measures all aspects of the construct.

For a study to be valid, <u>the measurement method must cover all relevant parts of the subject it is measuring</u>. If it doesn't do so, then the validity of the study is treatment because of content validity.

In this case, the construct we are studying (quality of a relationship) has three parts (belong, interdependence and intimacy). Since <u>the questionnaire doesn't include items tapping intimacy it is not covering all three parts of the construct</u> and therefore it is lacking content validity.
