#23. Use the following information to answer the next question.

In a testcross, the parent that is homozygous recessive for the genes being studied is called the testcross parent. The parent that has the dominant phenotype of the genes being studied is called the non-testcross parent.

Which of the following is NOT a reason that a testcross is a useful technique when studying the inheritance of a trait?
Select one:
a. The gametes produced by the testcross parent are determined from the testcross progeny.
b. A testcross can determine if an individual with the dominant phenotype is homozygous or heterozygous.
c. The relative frequencies of the different phenotypes among the testcross progeny can be used to map linked genes.
d. Because the testcross parent can contribute only recessive alleles, the alleles contributed by the other parent will be expressed in the offspring of the testcross.

my guess is b. Am i right?
