Question

( 2 )
Phenotypic ratio of a cross between
AaBb and aaBb, when both A and B are
haplosufficient and completely
dominant over their recessive
counterparts is
(1) 3:3:1:1
fü) 9:3:3:1
(ii) 1:1:1:1
five) 1:2:1:2 : 4:2:1:2:1​

Answer 1

Answer:

last one is the correct answer

Answer 2

Answer:

Explanation:

Last option s the correct one :4:2:1:2:1.

Phenotypic ratio  are of the following kind :27:9:9:9:3:3:3:1 ratio:

From  forked line diagram, a trihybrid cross produce a phenotypic ratio of 27:9:9:9:3:3:3:1.

This reveals  the phenotypes produced by the 64 genotypic combinations producing  from 8 different male gametes which can be able to  fertilize  8 different female gametes.
