Hey there! :)
To solve a Punnett square, we need to master the fields in the attached picture
In the question, the given keys are:
Dominant allele Y → yellow
Recessive allele y → green
Y | y
Y | YY Yy
Y | YY Yy
This would be the Punnett square for this question
Percentage of offspring to have yellow seeds?
Yellow is Y, then we should count which alleles had YY as a genotype?
YY = 2 out of 4, then 50%

NUCLEAR ENERGY
Every second of every day our Sun converts about 4.2 million metric tons (4,200,000,000 kilograms) of hydrogen into helium using a nuclear <span>fusion </span>process. During this nuclear reaction, a small portion of matter is converted to an enormous amount of energy. It is this output that provides the energy for photosynthesis and for heating our atmosphere and oceans.
In this lesson, you will learn the details of the nuclear fusion process. You will also learn about another important nuclear reaction called fission and some useful applications of it.
OBJECTIVES<span>Describe the process of nuclear fusion.Describe the process of nuclear fission.Identify some applications for nuclear reactions.List positive and negative factors associated with nuclear reactions.</span><span>VOCABULARY</span>
