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.
