An A/a;B/b dihybrid is testcrossed,and about ¾ of the progeny phenotypically resembles the dihybrid parent,while ¼ resembles the tester parent.If the dihybrid parent was selfed,what would be the expected phenotypic ratio in the progeny?

Question

Quizplus · Accepted Answer

The dihybrid testcross results suggest that the genes are linked, with the majority of progeny resembling the dihybrid parent. When the dihybrid is selfed, the expected phenotypic ratio for linked genes with complete dominance is 15:1.
