We think that dwarfism in river birch might be inherited as a single-locus, simple Mendelain trait. We have taken a pure breeding normal plant and crossed it with a a pure breeding dwarf plant. The resulting plants were self-pollinated with the following results: Normal River Birch 805 Dwarf River Birch 246 Perform a chi square analysis on this data using the following hypothesis: The mode of inheritance for plant height in the river birch is simple Mendelian. Calculate the chi square value without rounding and then round your final answer to three decimal digits and put it in the space provided.

Inheritance and Mendelian Genetics

Inheritance means the passing of traits to offspring from parents. These traits could be passed either through asexual reproduction or sexual reproduction. The offspring receives the genetic material from the parents. Mendelian inheritance is a certain biological inheritance that follows the rules and principles laid down by Gregor Mendel in 1865. The initial hypothesis was considered wrong, but other inheritance theories modified the concept of inheritance and thus genetics.
