mendel’s experimental method involved using true breed parental plants for each of the traits he studied in the monohybrid cross. why was this vital to the outcomes of the experiment?

Given what we know about Mendel and his experiments, we can confirm that the benefit of his using true breed parental plants was that it added accuracy and precision to his experiment.

The experiment mentions the use of true breed parental plants for each trait that was studied. A true breed or true-breeding organism is one that will ensure the inheritance of certain physical traits to its offspring through every generation. This is also commonly referred to as a purebred.

The importance of this detail in Mendel's experiments is that it functions as the control variable for the experiment. This is a variable that is maintained constant so that when a change occurs, we can attribute it to other factors and therefore add accuracy to the experiment. Therefore, by starting with purebred parental plants, Mendel could better identify the cause of inheritance for the traits.

Practice using the computer model. Select each marker to see what it does. Here is a summary you can refer back to as you complete your experiment.
Carbon Dioxide Emissions Slider: You will use the arrows to change the amounts of carbon emissions.
Time Step Size: This will allow you to view the data every 5 years or every 10 years.
Start Over: Use this to reset the model if needed.

The current carbon emissions are 9.8 gigatons, or 9.8 billion tons. Complete all three scenarios to find out what happens to the global temperature if these emissions stay the same, decrease, or increase over the next century. Follow the instructions in the Data section of this report.

Data:
For each scenario, record the carbon dioxide emission rate and the global temperature. The data for the years 1960–2010 are already filled out for you.

Scenario One: Carbon dioxide emissions stay the same
Set the carbon dioxide emissions rate to 9.8 gigatons.
Set the time step size to 10 years.
Select step forward until you have the data through the year 2110.
Record the data in the table below.
Year Carbon Emissions (gigatons) Temperature (Fahrenheit)
1960 4.2 57.2
1970 5.8 57

Set the time step size to 10 years.
Select the step forward button once.
Decrease the carbon dioxide emissions by 0.2 and press step forward.
Continue stepping forward once, decreasing the carbon emissions each time, until you reach 2110.
