a pea plant with genotype pp (purple flowers) mates with a plant with the genotype pp (white flowers). the dominant allele p codes for purple flowers. the possibility that the offspring will have purple flowers is . if an offspring from this cross mates with a pp, the possibility of homozygous dominant genotype for the flowers will be .

a) The possibility that the offspring will have purple flowers is 100%

b) The possibility of homozygous dominant genotype for the flowers will be 0%

Explanation:

a)

Given

"P" is the dominant allele representing the purple color

"p" is the recessive allele representing the white color

When "PP" is crossed with "pp", the following offsprings are produced

PP

pPpPp

pPpPp

All the the "Pp" have purple color as "Allele P" (Purple color) is dominant over "Allele p" (white color)

Thus, the possibility that the offspring will have purple flowers is 100%

b)

Given

Offspring produced in part (a) mates with "pp" i.e "Pp" mates with "pp"

Now, when "Pp" mates with "pp" following offsprings are produced

Pp

pPppp

pPppp

Thus, out of four ofsprings there is no offspring which has homozygous dominant genotype (PP) for the flower.

Hence, the possibility of homozygous dominant genotype for the flowers will be 0%

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.
