In rabbit, two recessive genes produce a solid body colour and long hair in contrast to dominant spotted body colour and short hair. The result of a cross between heterozygous spotted short haired rabbit to solid long haired rabbit gives spotted, short haired 48, spotted long haired 5, solid short haired 7, solid long haired 40, total 100. In terms of cross over units, how far are these two genes on the chromosome?
View answer and explanation
Correct option: C
12 map units
Option C (12 map units) is correct because the recombination frequency, calculated from the recombinant offspring, directly corresponds to the map distance between the genes.
