Mendel peas crossing between true breeds

Anonymous

Question description

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 F2 generation:
80 tall, violet flowers
36 tall, white flowers
39 dwarf, violet flowers
5 dwarf, white flowers

how many tall flowers with violet flowers were expected?

how many tall plants with white flowers were expected.

how many dwarf plants with violet flowers were expected?

how many dwarf plants with white flowers were expected?

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.

Can the deviation of observed values from expected values be attributed to random chance?
