1.Place a small piece of masking tape on each side of two coins.Each coin represents a single parent.Each side of one coin represents one allele on one gene.

2.On each coin, write T on one side and "t" on the other so that each "parent" is heterozygous.

3.Toss the coins 100 times.In your observations, write the combinations of genes that appear.

NB T= Tall plant; t= short plant

Data analysis

i)Calculate X² for this experiment. (use table; show working)

ii)Degree of Freedom =

iii)The critical value of X² at 0.05,=

iv)Is there a significant difference between your observed and the expected value? Explain your answer.

-Include results of when the coin was flipped in a table format
