recombination frequency of 5% with the


gene C and this grecombination frequency of 15% withene C has (^)
the gene A, it is possible to assert that
the gene A is 20 centimorfrom the gene B and that between themgans distant (^)
lies the gene C at 15 centimorgans of
distance from the gene A.



  1. Is crossing over important
    for the diversity of biological
    evolution?


Sexual reproduction and recombination
of linked genes (crossinalong with mutations, the g over) are,main
instruments of biological variability.


Sexual recombinations beproduction allows matween genes situated ny (^) in
different chromosomes. Crossing over,
however, is threcombination of alleles locatee only means to provided in a
same chromosome. Crossing over
probably emaintained by the evolution merged and has beenbecause of (^)
its importance to biological diversity.
