Question 1
In the analysis of quantitative traits, positions on chromosomes called quantitative trait loci (QTLs) are often discussed. In the same context, restriction fragment length polymorphisms (RFLPs) are also discussed. What is the relationship between QTLs and RFLPs?
Question 2
A "marker" in a genetic sense usually represents a site along a chromosome where a specific nucleotide sequence exists. Which specific phrase is used when such markers are identified by restriction endonucleases and a particular set of DNA fragments is generated?
