What map unit(Centimorgan) is adopted in the construction of genetic maps?

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
Correct Answer
DA unit of distance between genes on chromosome, representing $$50\%$$ cross over

Solution

$$1$$ map unit represent $$1\%$$ cross over.
Map unit is used to measure genetic distance. This genetic distance is based on average number of cross over frequency.
So, the correct answer is 'A unit of distance between genes on chromosomes, representing 1%
1% cross over'
