Document Summary
Genes located on the same chromosome may be inherited together in genetic crosses they do not assort independently because the chromosome is inherited in meiosis. Linked genes genes on the same chromosome. Linkage the phenomenon of genes being located on the same chromosome. 11. 1a the principles of linkage and recombination were determined with. Thomas h. morgan: used the fruit fly (drosophila melanogaster) to investigate. Alfred sturtevant: developed insight that resulted in the construction of the first genetic map showing the relative order of genes on a chromosome and estimated the distance separating the genes. Made using the process of recombination (detectable) occurring on the space separating 2 genes on the chromosomes paired during meiosis far apart = more likely to be separated during meiotic crossing-over. Morgan"s genetic symbolism used to understand the crosses. Normal or wild-type genotype a mutant. Mutant alleles based on the altered phenotype of the organism that expresses them. Wild-type allele superscripted + sing (antp+)
