Imagine that you attempted to recreate Mendel's work with garden peas. You began by crossing true breeding violet-flowered, tall plants with white-flowered dwarf plants.
After self-crossing the F1 generation, you obtain the following phenotypes in the F2generation:
80 tall, violet flowers
36 tall, white flowers
39 dwarf, violet flowers
5 dwarf, white flowers
Part A
How many tall plants with violet flowers were expected?
Express your answer as a whole number.
Part B
How many tall plants with white flowers were expected?
Express your answer as a whole number.
Part C
How many dwarf plants with violet flowers were expected?
Express your answer as a whole number.
Part D
How many dwarf plants with white flowers were expected?
Express your answer as a whole number.
Part E
Use a chi-square analysis to test the hypothesis that the F2 data for stem length (tall:dwarf) is consistent with Mendel's law of segregation.
Calculate the chi square value.
Express your answer to two decimal points (example: 100.00).
Part F
Can the deviation of observed values from expected values be attributed to random chance?
yes or NO
Use the probability chart to answer this question.

yes
no
Part G
Use a chi-square analysis to test the hypothesis that the F2 data for stem length (tall:dwarf) and flower color (violet:white) is consistent with Mendel's law of independent assortment.
Calculate the chi square value.
Express your answer to two decimal points (example: 100.00).
Part H
Can the deviation of observed values from expected values be attributed to random chance?
