Explain the example of complete linkage

Dear Student,

Complete linkage is the state in which two loci are so close together that alleles of these loci are virtually never separated by crossing over.When the genes are tightly linked , resulting in very low percentage of recombination. In such condition, only parental or non cross over type of gametes are formed.

 Meiosis, a type of cell division that produces variation through crossing over between non-sister chromatids of homologous chromosomes. Some genes present close to each other on the same chromosome are tightly linked when compared to other genes. These linked genes produce less recombination frequency, i.e., there is less chances of crossing over occuring between these genes. These genetically linked regions tend to stay together during meiosis. Loosely linked genes produces more recombination (non parental types) frequency. The genes which are 0% linked can produce 100% recombination and the genes which are 100% linked (completely linked) produce 0% recombination.

Regards
