15. Which of the following statements regarding "Genetic Mapping" are CORRECT?
(A) Crossing of a homozygous wild type with a mutant that is heterozygous for a dominant mutation will result in F₁ progeny of which three-fourths show the mutant phenotype
(B) A genetic change from GAA to GAT in the noncoding region is an example of single nucleotide polymorphism (SNP)
(C) Microsatellite DNA consists of a repeat length of 1-13 base pairs, which only occur in the noncoding region but not within the transcription units
(D) A haplotype is a set of closely linked genetic markers on a particular chromosome that tend to be inherited together

(E) In linkage analysis, when the recombination frequency between the gene of interest and a marker is very high, then the gene is likely located near of that marker
