Vedclass · Answer

(D) The cross $AaBbCc 	imes AaBbCc$ represents a trihybrid cross involving three independent genes.For a single gene cross $(Aa 	imes Aa)$,the phenotypic ratio is $3:1$.For a trihybrid cross,we apply the product rule of probability by multiplying the ratios of the three independent monohybrid crosses: $(3:1) 	imes (3:1) 	imes (3:1)$.Expanding this: $(3:1) 	imes (9:3:3:1) = 27:9:9:9:3:3:3:1$.This ratio represents the $8$ different phenotypic classes in the $F_2$ generation.

What will be the phenotypic ratio produced by the cross $AaBbCc \times AaBbCc$?
