A true-breeding white strain of flower was crossed with a true-breeding orange strain. All of the F1 progeny were white in phenotype. When the F1 offspring were crossed with one another, the following offspring phenotype frequencies were obtained in the F2 generation: F2: 98 White

34 Orange

11 Yellow

Using this information, postulate the role of mutant genes and their products in producing the observed phenotypes:
(a) designate alleles and give the general genotypic formula for parental strains and the F1,
(b) give the general genotypic formula that defines each color class and
(c) explains the phenotypic ratio obtained [say what it is] (See attached Table 1), AND
(d) diagram/draw a metabolic pathway that explains the formation of each pigment (or lack thereof).

the transfer of energy between two molecules spaced just nanometers apart plays a key role in many technologies, including photovoltaics, quantum information systems, lighting, and sensors, as well as in biophysics to measure nanometer distances and in photosynthesis. but an open question in this area is what effect, if any, the surrounding photonic environment has on this nanoscale energy transfer. by designing and performing a carefully controlled experiment to answer this question, scientists have settled the debate and found clues to improving the efficiency of many of the technologies that rely on this process.

in 1859, charles darwin set out his theory of evolution by natural selection as an explanation for adaptation and speciation. he defined natural selection as the "principle by which each slight variation [of a trait], if useful, is preserved".
