1.What proportion of purple kernels is expected in the progeny of the monohybrid cross in Experiment 1?
2.Fill in the table below with the data you collected during Experiment 1 Purple Kernels Yellow KernelsRow 12010Row 21614Row 3246Row 4255Row 5219
3.Data Analysis3.Use the data you collected in Experiment 1 to calculate the percentage of each phenotype.
4.Suppose you observed 240 progeny that resulted from a monohybrid cross and involved genes that obeyed Mendelian inheritance, how many heterozygous progeny would you expect to observe?

3.4.According to your results in Experiment 2, what would be the correct hypothesis to test tosee if the traits were inherited through Mendelian genetics? Record this answer for use in a later question.
5.For the cross in Experiment 2, how many degrees of freedom are there? Record this answer for use in a later question.
6.Determine the Χ2value for Experiment 2 using the following equation. Record your answer for use in a later question.
7.8.Use the degrees of freedom and Χ2value from earlier questions to determine the pvalue for Experiment 2 using the table of critical values for Χ2. Record your answer for use in a later question. The p value is greater than 0.05 which proves the hypothesis.Conclusions1.Use the hypothesis, degrees of freedom, Χ2, and pvalue determined in earlier questions toconclude whether corn #2 is following Mendelian genetics. Explain your reasoning.
2.3.If you crossed Cat #1 and Cat #2 and observed two unlinked traits that follow Mendelian genetics, what must the genotype and phenotype of Cat #2 be?
Coat color:Dominant = white (W)Recessive = some color (w)LLWW,LLWw, LLww, lLww, llWW,4.In a test population of 1000 people, 200 display albinism. You hypothesize that this trait follows Mendelian genetics with a 3:1 ratio of non-albinism to albinism. Use the Χ2test to determine whether the data support the hypothesis or not. Show your steps and explain your reasoning.
