Question

Gender identification using STR analysis:

a. looks at hypervariable sequences on the Y-chromosome
b. is not done
c. can be used for identification of intersex individuals
d. utilizes the amelogenin locus

The Power of Discrimination

is not important because it excludes data from ethnic races

is high for RFLP techniques

is increased with the number of alleles studied

is due to low hypervariability at each locus

Y-STRs are found on the:

does not require allelic ladders for reference standards

Y-chromosome but also found on the X-chromosome at the telomere

Y-chromosome and specific to males

is hemizygous in females

a.

is not important because it excludes data from ethnic races

b.

is high for RFLP techniques

c.

is increased with the number of alleles studied

d.

is due to low hypervariability at each locus

Explanation / Answer

Ans-1 the correct option is (D) i.e utilizes the amelogenin locus.

Because it is a sex specific locus its allele binding pattern helps in sex determination.

Ans-2 the correct option is (C) i.e. increase with the number of alleles studied because more the number of alleles will be more the information we will get.

Ans-3 the correct option is (c) i.e y chromosome and specific to males because it is identical to parental lineages.
