An allele is a viable DNA (deoxyribonucleic acid) coding that occupies a given locus on a chromosome. Usually alleles are sequences that code for a gene, but sometimes the term is used to refer to a non-gene sequence. An individual's genotype for that gene is the set of alleles it happens to possess.
Genetic counselors typically receive a bachelor's degree in biology, social science or a related field, and then go on to receive specialized training, so I would say your answer would be B.) must have a degree in biology or genetics. I hope this helps!
The independent variable is the one variable you manipulate in the experiment
The dependent variable (or responding variable) changes as a result of the independent variable
A good passing current is a small wave for example.
Manipulated Variable:The speed working on maths problems
Responding Variable: The group that use¬ using a calculator
