Answer:
Punnet squares are basically how you can somewhat "predict" the outcome of gene pools.
Explanation:
As you can see, the capital letters (RY) are dominant alleles meaning they will be the trait that shows no matter what. the lower case letters (ry) show recessive traits and will only show if paired with another recessive gene.
Genotype is the actual makeup so the letters. (Rr, Ry, ry... etc.)
Phenotype is the trait that shows such as brown hair, blue eyes, etc.
Frequency is just how many times the gene shows up and put as a fraction or percent.
Scientific reasoning requires following the scientific method.
1. You foremost make an observation about the universe.
2. Make a hypothesis as to why that phenomenon is the way it is.
3. Design an experiment to test your hypothesis. Hypotheses can be thought of as "predictions"
4. Finally draw a conclusion based on the results of your experiment. Was your hypothesis proven to be valid?
