Question 1 From a testcross Aa aa in which A represents red

Question 1

From a testcross A/a × a/a, in which A represents red and a represents white, use the ² test to find out which of the following results statistically fits with a predicted Mendelian pattern of gene segregation. The test evaluates where deviations from Mendelian ratios is most likely due to chance. Use a 95% confidence level as the cutoff: p values of less than 0.05 are considered to not display \"fit,\" and reveal a significant deviation from the hypothesis.

Testcross result: 120 red, 100 white

Question 2

Question 3

You have three jars containing marbles, as follows:

jar 1: 600 red and 400 white
jar 2: 900 blue and 100 white
jar 3: 10 green and 990 white

If you blindly select one marble from each jar, calculate the probability of obtaining a red, a blue, and a green.

Solution

2. All progeny match the phenotype of the mother, so the genes may be maternal.
