An Example of Increased Recombination in Gossypium1
- Joshua A. Lee2
A chromosome bearing a marked segment was transferred from the diploid species Gossypium raimondii Ulb. to the teraploid species, Gossypium hirsutum L. Upon mating with the homeologous G. hirsutum chromosome, the segment gave 2.4% recombination for the two markers used. When the genes were later recombined from the repulsion phase, the recombination value increased to an average of 20.2%. This increase was attributed to accelerated recombination in homologously paired segments that appeared in the intercalary region following initial breakage.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
