Why did (or could) the class data cause you to reject the null hypothesis used in each case? How could we have made more accurate null models to test the idea that students in the class have the expected distribution by gender and month of birth? Part 3 Genetics application – crossing true-breeding yellow and green pea plants, Mendel allowed the F1 plants to self. He observed 6022 yellow and 2001 green pea plants resulting from this F1 self-cross. He used these data to develop his law of segregation. Write the genotypes for the true-breeding yellow and green plants, the F1 hybrids, and the green and yellow progeny from the F1 self-cross. Be sure to indicate which allele is dominant with your notation. Using a chi-squared test, determine if the 6022 yellow and 2001 green pea plants Mendel observed are consistent with his law of equal segregation. Be sure to set up a table of observed and expected data and record the chi-squared value, degrees of freedom, approximate p-value (use the table above), and indicate whether the null hypothesis should be rejected.
