What map unit (Centimorgan) is adopted in the construction of genetic maps?
Options
- AA unit of distance between two expressed genes, representing 10% cross over.
- BA unit of distance between two expressed genes, representing 100% cross over.
- CA unit of distance between genes on chromosomes, representing 1% cross over.
- DA unit of distance between genes on chromosomes, representing 50% cross over.
Correct answer
C. A unit of distance between genes on chromosomes, representing 1% cross over.
Step-by-step solution
1 map unit or centimorgan is equivalent to recombination between two genes. If was Sturtevant who first suggest that frequency of recombination can be used to depict relative distance between the genes. crossing over is known as Morgan (M)
