Cross a YyLl (heterozygous parent with dominant traits) with yyll (homozygous parent with recessive traits). Look at the number of genotypes of the F1 generation:
YyLl: 400
Yyll: 100
yyLl: 100
yyll: 400
How far apart are Y and L? Give your answer in map units. (Hint: Add the numbers of the two recombinant types, divide by the total number of offspring, and multiply by 100.)
