Color of petals is controlled by two genes by the pathway

Reference no: EM13528926

(a) In sweet peas, the color of petals is controlled by 2 genes (Band D) by the pathway -
Gene B Gene D
White precursor -------> Red pigment --------> Bluepigment
What would be the the flower colors of B_D_, B_dd, bbD_ and bbddgenotypes?
In a cross of BBDD x bbdd, what would the F2 progeny phenotypicratios be?
(b) What if the pathway to blue petals was as given below-
Gene B
White precursor --------> Blue pigment
Gene D inhibits Gene B
What would be the the flower colors of B_D_, B_dd, bbD_ and bbddgenotypes?
In a cross of BBDD x bbdd, what would the F2 progeny phenotypicratios be?
