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.

Fruit bats in central america eat bananas and other fruits. banana plants rely on bats for pollination. what would be the most likely consequence on the banana crop if fruit bats were eliminated from the area? the banana crop would increase because bats would stop eating the crops. the banana crop would decrease because bats would no longer pollinate the crops. the banana crop would remain constant because bees would replace the bats. the banana crop would remain constant because the plants would adapt using asexual reproduction.
