One of the goals of the <u>a) Causal</u> research is to understand the influence of the independent <u>variables</u> on the dependent <u>variable</u>.
<h3>What is causal research?</h3>
Unlike descriptive research, which describes what is going on or what exists, causal research or “experimental study” is designed to determine whether one or more variables (independent variables) cause or affect the value of another variable (dependent variable).
An independent variable is a variable that the researcher changes to determine the dependent variable.
<h3>Answer Options</h3>
a) Causal research
b) Probability sampling
c) Descriptive research
d) Exploratory research
e) Nonprobability sampling
Thus, one of the goals of the <u>a) Causal</u> research is to understand the influence of the independent <u>variables</u> on the dependent <u>variable</u>.

Answer:
Explained
Explanation:
Concordance: This is a term used in genetics. This term is used to imply the presence of the same trait/characteristic in both the members of a pair of twins.
Twins can be of 2 types. They are monozygotic twins and Dizygotic twins.Monozygotic twins are identical twins, i.e. they are formed from one zygote that later splits into two forming two embryos.
Dizygotic twins are non-identical twins or fraternal twins formed from the fertilization of two different eggs with two different sperm cells.
Concordance values can be calculated as:
C = Number of concordance pairs/(number of concordant pairs + number of discordant pairs)
Monozygotic twins generally have a concordance value of 44% for a specific trait.
Dizygotic twins have a concordance value of less than 5 % for a trait.
For identical twins the number of concordant pairs would be 50 out of 100.concordant pair would be
For non-identical twins, the number of concordant pair would be 17 out of 100.
For a recessive trait to be expressed, both the parents should be heterozygous for that trait.
