If two loci Rr and Ww are linked and are 14 map units apart

If two loci R/r and W/w are linked and are 14 map units apart, and an Rw/rW individual is testcrossed, you will obtain:

Solution

The map distance is 14 mu indicates that the recombination frequency between the two genes is 14%. Therefore, the frequency of recombinants is 14% whereas the frequency of parental genotypes is 86%. The following are the genotype frequencies of the offspring:

* Rw / rw - 43%

* rW / rw - 43%

* RW / rw - 7%

* rw / rw - 7%
