Given what you know about photoperiodism in Arabidopsis, what phenotype are you looking for and under what photoperiodic conditions would you perform the experiment? delayed flowering in long days delayed flowering in short days same flowering in short days early flowering in short days same flowering in long days early flowering in long daysIn roses, the synthesis of red pigment is by two steps ina pathway, as follows:colorless intermediate gene Pmagenta intermediate red pigment gene Qa. What would the phenotype be of a plant homozygousfor a null mutation of gene P?b. What would the phenotype be of a plant homozygousfor a null mutation of gene Q?c. What would the phenotype be of a plant homozygousfor null mutations of genes P and Q?d. Write the genotypes of the three strains in parts a, b,and c.e. What F2 ratio is expected from crossing plants fromparts a and b? (Assume independent assortment.)1a.Discovery of genes controlling Gibberellic Acid (GA) synthesis and perception became very important during the Green Revolution, and remain important today. Why? Select one: a. Mutants with reduced GA levels are dwarfs. Many dwarf plants were important for the Green Revolution because the shorter plants can invest more energy into economically important parts like seeds (instead of stem length). b. Mutants with reduced GA levels are more resistant to herbivore damage (like caterpillars), increasing plant yields. c. Mutants with reduced GA levels allowed farmers to control fruit ripening more accurately. d. Mutants with reduced GA levels have increased photosynthesis 1b. What features are important for overall plant form? Select one: a. Iterative development and capillary action b. Iterative development and apical dominance c. Apical dominance and stomatal conductance d. Phyllotaxis and capillary action
