A student is considering a cross in which two physically linked genes are being investigated. The results of the cross yield offspring in the following phenotype classes:

35% Parental type 1
35% Parental type 2
15% Recombinant type 1
15% Recombinant type 2

When reporting the distance between linked genes, which of the following is a correct representation for the distance between two genes that exhibit a 30% recombinant progeny in a given cross?


30 map units (mu).


30 centiMorgans (cM).


Both Choice 'A' and 'B' are correct representations.


None of the above are correct representations.
