Who was the first to map chromosome what formed the basis for it?

Accordingly, who discovered chromosome mapping?
The First Genetic-Linkage Map. One hundred years ago, in 1913, Alfred H. Sturtevant helped lay the foundations of modern biology by mapping the relative location of a series of genes on a chromosome.
Similarly, how are chromosome maps created? Chromosomes are made of DNA, and genes are special units of chromosomal DNA. Each chromosome has a distinct banding pattern, and each band is numbered to help identify a particular region of a chromosome. This method of mapping a gene to a particular band of the chromosome is called cytogenetic mapping.
Accordingly, what did Alfred Sturtevant discover?
Sturtevant, Alfred H. (1891-1970) was an American geneticist and the first to discover the procedure for gene mapping. This ability to determine the positions of genes on a chromosome made possible the Human Genome Project, an attempt to identify and map the entire set of human chromosomes.
How were the first human linkage maps constructed?
The first constructed maps of the human genome were genetic linkage maps, built by measuring the recombination rates between genetic markers, which usually were blood groups and serum proteins. Rates of recombination vary by chromosome position, GC content, and the density of selected repeat units (Yu et al.
