Scientific method is an organized steps of procedures that scientists used to study and gather knowledge about different phenomenons. The systematic steps of scientific method start with observation, the observed phenomenon usually make a scientist to ask questions that he doesn't have an answer to. This will prompt him to formulate an hypothesis and set up an experiment to see if his hypothesis is true or not.

By following these steps, scientists usually obtain useful information that bring progress and advancement to humanity.
Answer:
<em>The correct option is Although the F1 generation will all show the dominant trait, the offspring will all be heterozygous and increase chances of future variation.</em>
Explanation:
The cross for the offsrings that will be produced by F1 generation is shown below:
a a
A Aa Aa
A Aa Aa
As we can see that all the offsprings in the F1 generation will have heterozygous genes but only the dominant trait will be seen in the phenotype of the F1 generation.
A cross between the F1 generation will give the following results:
A a
A AA Aa
a Aa aa
This cross shows that there will be increases genetic and phenotype variations in offsprings that will be produced by the F1 plants.
