In tomatoes, tall (D) is dominant over dwarf (d) and smooth fruit (P) is dominant over pubescent fruit (p), which is covered with fine hairs. A farmer has two tall andsmooth tomato plants, which we will call plant A and plant B. The farmer crosses plants A and B with the same dwarf and pubescent plant and obtains the following numbers of progeny

a. The genotypes of both plant A and plant B are DdPp

b. In plant A, Gene D and Gene P link as cis configuration

c. In plant B, Gene D and Gene P link as cis configuration

d. In plant A, Gene D and Gene P link as trans configuration

e. In plant B, Gene D and Gene P link as trans configuration

Some xanthophylls also participate in energy dissipation such as in light conversion of Violaxanthin to Zeaxanthin with antheraxanthin as the intermediate and vice-versa, which of the following statements is CORRECT?

a.) The conversion of Violaxanthin to Zeaxanthin a singlet oxygen is removed with the help of co-factor Ascorbate and violaxanthin de-epoxidase under high PPFD

b.) Zeaxanthin is oxidised into violaxanthin with the help of NADPH and oxygen under low PPFD

c.) Conversion of Violaxanthin to Zeaxanthin a singlet oxygen is removed with the help of NADPH and water under low PPFD

d.) Zeaxanthin is oxidised into violaxanthin in presence of enzyme known as violaxanthin de-epoxidase and co-factor Ascorbate under high PPFD

Protection against photodamage is a multilevel process, excited state of chlorophyll is not rapidly quenched by photochemistry it can react with molecular oxygen to form toxic photoproducts such as as singlet oxygen (1 O2*) what can damage if this second line of defense also fails to eliminate the reactive photoproducts?
