Vedclass · Answer

(A) The distance between two linked genes is measured in map units (centimorgans),which is directly proportional to the recombination frequency (gene exchange rate).According to the principle established by Alfred Sturtevant,$1\%$ recombination frequency is equal to $1$ map unit (or $1$ centimorgan).Given that the gene exchange rate is $30\%$,the distance between the two genes is $30$ map units.Therefore,the correct option is $A$.

If the gene exchange rate (recombination frequency) of two linked genes is $30\%$,then the distance between these two genes is:
