Because linkage maps are inherited by the cross over frequencies
Because linkage maps are inherited by the cross over frequencies
Use linkage maps
A gene map is a chromosomal map, which shows the location of genes. Based on inherited genes, a linkage can be used to create a gene map.
A linkage map is a genetic map that shows the relative positions of genetic loci on a chromosome based on recombination frequencies, while a sequencing map provides the exact order and position of nucleotides in a DNA sequence. Linkage maps are based on genetic distance, whereas sequencing maps provide physical distance information. Linkage maps are useful for studying genetic inheritance patterns, while sequencing maps are crucial for understanding the actual genetic code.
The data collected when all the members of a population have been genotyped (scored) with a set of molecular markers can be used to make a linkage map.
Genetic linkage was first discovered by the British geneticists William Bateson and Reginald Punnett shortly after Mendel's laws were rediscovered. The understanding of genetic linkage was expanded by the work of Thomas Hunt Morgan. Morgan's observation that the amount of crossing over between linked genes differs led to the idea that crossover frequency might indicate the distance separating genes on the chromosome. Alfred Sturtevant, a student of Morgan's, first developed genetic maps, also known as linkage maps.

Astrolabes and maps
Alfred Sturtevant used gene linkage to create gene maps by analyzing the patterns of inheritance of genes located on the same chromosome. By studying how often certain genes were inherited together, he was able to determine their relative positions on the chromosome. This information allowed him to create the first genetic maps, which showed the linear order of genes along a chromosome.
Astrolabes and maps
it helps relate that part of the world to the rest. also itshows the actual size it would be
Yes. There are always people collecting Marine relics and memoribilia. Try ebay, or a collector show. I collect maps that relate to the Italian Campaign. See: http://www.custermen.com/Maps/ArmyMaps.htm
