Problem:
The Kidd blood group in primates is inherited as a single gene with two codominant alleles (Jka and Jkb). We would like to verify that this locus actually follows simple Mendelian inheritance with codominant alleles in gibbons. We have a pure breeding population of Type Jka and a pure breeding population of Type Jkb.
We create an F2 population and test for the antigens.
Jka: 30
Jka Jkb: 63
Jkb: 35
Perform a chi square analysis on this data using the following hypothesis:
The mode of inheritance for the Kidd blood group in gibbons is simple Mendelian with codominant alleles.
Question: Calculate the chi square value and place it in the space below.
Round to three decimal places. Please show your work.
