1. A. You cannot reject the null hypothesis. Explanation: For Dihybrid cross, there are four phenotypes in 9:3:3:1 ratio. degree of freedom df= number of phenotypes -1. Number of phenotypes = 4. So, df = 4-1= 3. For three degree of freedom when the p-value is 0.05, critical value is 7.815. 7.815>6.5. So we accept the null hypothesis that genes are assorted independently and follow Mendelian inheritance pattern 2. Degree of freedom df = number of phenotypes -1. In the given cross there are three phenotypes- blue eyes, hazel eyes and brown eyes. So degree of freedom df = 3-1 = 2. So answer is option B. 2 3. The greater the x^2 value and the lower the P value 4. A genetics engineer was attempting to cross a spotted purple orchid with a striped purple orchid. She predicted a phenotypic outcome of the traits she was observing to be in the following ratio 1 stripes only: 2 spots only: 3 both stripes and spots. When the cross was performed and she counted the individuals she found 22 with stripes only, 49 with spots only and 62 with both. According to the

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
