In Gregor Mendel’s experiments with peas he observed 315 round and yellow, 108 round and green, 101 wrinkled and yellow, and 32 wrinkled and green. According to his theory of heredity the numbers should be in the proportion of 9 : 3 : 3 : 1.

• Is there any reason to doubt his theory at the level of 0.01 or 0.05 significance?

• What is the P value?

Gregor Johann Mendel, the Father of genetics, conducted his groundbreaking experiments with peas. The table below shows the results of one of his experiments (adapted from Cramer, 1999). With a sample of peas, the characteristics were distributed as follows: ------------------------------- Phenotype Number ------------------------------- Round and Yellow 315 Round and Green 108 Angular and yellow 101 Angular and Green 32 ------------------------------- Test the hypothesis that the distribution of characteristics in the sample points to a population where phenotype distribution is random....

When Gregor Mendel conducted his famous genetics experiments with peas, one sample of offspring consisted of 428 green peas and 152 yellow peas. a) Find a 95% confidence interval estimate of the proportion of yellow peas. b) Based on his theory of genetics, Mendel expected that 25% of the offspring peas would be yellow. Do the results contradict Mendel’s theory? Why or why not?

3. When Gregor Mendel conducted his famous hybridization experiments with peas, one such experiment resulted in 580 offspring peas, with 26.2% of them having yellow pods. According to Mendel’s theory, 25% of them should have yellow pods. Use a .05 significance level to test the claim that the proportion of peas with yellow pods is 25%. a. Check your assumptions (SINS).    b. Set up the null and alternative hypotheses. ?0:______________________ ?1:______________________ c. You will run the following type of...

In one of Mendel’s hybridization experiments with peas, the probability of offspring peas having green pods is ¾ or 0.75. Assume that whether offspring pea has green pods is independent of whether the green pod is a different color. Find the probability that exactly 13 out of 20 offspring peas will have green pods. Find the probability that 13 or fewer out of 20 offspring peas will have green pods. According to a Consumer Report, the mean replacement time of...

Consider the problem regarding the genetics of crossing two types of peas. The Mendelian theory states that the probabilities of the classifications (a) round and yellow, (b) wrinkled and yellow, (c) round and green, and (d) wrinkled and green are 9=16 ; 3=16; 3=16; and 1=16, respectively. Suppose that from 160 independent observations, the observed frequencies of these respective classifications are 85; 35; 27 and 13. Test at the 1% level of significance if these data are consistent with the...
