We think that dwarfism in river birch might be a simple Mendelian trait. We have taken a pure breeding normal plant and crossed it with a a pure breeding dwarf plant. The resulting F1 plants were selfed and the F2 data is presented below:

Normal River Birch 802

Dwarf River Birch 296

Perform a chi square analysis on this data using the following hypothesis:

The mode of inheritance for height in river birch is simple Mendelian.

What is the calculated chi-square value? Round to three decimal places.
