The most notable activist of them was Martin Luther King Jr. of the Southern Christian Leadership Conference, or the SCLC (Martin Luther King, Jr. Biography). Throughout the 1960s, King engaged in various civil rights boycotts and protests, helping to further the movement and gaining its eventual victory.
locus the specific point on a chromosome where the gene is found Source: Jenkins, John B. 1990. Human Genetics, 2nd Edition. New York: Harper & Row ... A locus (plural loci), in genetics, is the specific location or position of a gene, DNA sequence, on a chromosome. Each chromosome carries many genes; humans' estimated 'haploid' protein coding genes are 20,000-25,000, on the 23 different chromosomes. [en.wikipedia.org/wiki/Locus_(genetics)]
A quantitative trait locus is a section of DNA which correlates with variation in a phenotype. Usually the QTL is linked to, or contains, the genes which control that phenotype. QTLs are mapped by identifying which molecular markers correlate with an observed trait. This is often an early step in identifying and sequencing the actual genes that cause the trait variation.
