ISSR is generally a dominant STS DNA marker. Nonetheless, with validated experimental evidence (e.g. laboratory and population genetics data), the marker can be used in codominance marker genotyping. Briefly explain each case below:
a) Codominant marker targets specific locus and reveals allelic variations in that locus among DNA samples.
b) Dominant marker: primers can complement other repeat sequences or in multiple loci thereby non-specificity in sampled genomes.
Select all that apply: A SNP (single nucleotide polymorphism) is similar to an STR (short tandem repeat) in that:
a) an individual can have many different copies of specific SNP or STR
b) they both cause diseases
c)they are sequences that have many possible variants
d) an individual has one copy of this region of the genome from each parent.
How might the Hardy Weinberg relationship be used to evaluate a new SNP genotyping technology using multiple individuals from a population? Group of answer choices
a)If genotypes match the reference genome, the technology is sound. Otherwise, the technology may have problems accurately calling SNPs.
b)If observed phenotypes follow Hardy Weinberg, the technology is sound. Otherwise, the technology may have problems accurately calling SNPs.
c)If genotypes and allele frequencies follow Hardy Weinberg, the technology is sound. Otherwise, the technology may have problems accurately calling SNPs.
d)None of the above
