jenyasd209 [6]

Answer:

Given,

Colourless molecule is converted to black pigment by enzyme A. Black pigment is converted to agouti pigment by enzyme B.

Parent 1: AAbb = Black

Parent 2: aaBB = Colourless

AAbb X aaBB = AaBb (F1) The entire progeny is agouti coloured since dominant alleles for both the genes are present.

When AaBb X AaBb according to dihybrid cross in F2 :

A_B_  = 9 ( Agouti )

A_bb  = 3  ( Black )

aaB_  = 3  ( Colourless )

aabb   = 1 ( Colourless )

Hence genotypic ratio is 9 : 3 : 3 : 1

and phenotypic ratio is 9 (agouti) : 3 (black) : 4 (colourless)
