In garden peas, inflated pod shape (I) is dominant to pinchedpod shape (i) and yellow pea colour (Y) is dominant to green (y)pea colour. Plants heterozygous for these characteristics wereselfed (note that this is not a test cross), and the followingnumbers of phenotypes were seen in the progeny: 556 inflated,yellow; 193 inflated green; 184 pinched, yellow; 61 pinched greenTest the data for the involvement of two independently assortinggenes using the Chi-square test (don’t forget to state your NullHypothesis).
