Q.
Study the given test cross and choose the correct option for $F_{2}$-generation
A) Hybrid cross (9 : 3 : 3 : 1)
B) Hybrid cross (3 : 1)
C) Dihybrid cross (12 : 4)
D) Dihybrid linked gene cross (3 : 1)
Explanation
Dihybrid linked gene cross (3 : 1) Linked Gene The linked genes do not show independent assortment but remain together and are inherited en-block producing only parental type of progeny. They give a dihybrid ratio of 3 : 1 and a test cross ratio of 1 : 1 Dihybrid ratio of two linkage genes
