When Mendel experimented with crossing different types of peas, he noted both the color (green or yellow) and the shape (round or wrinkled) of the peas produced. The table below gives the predicted percentage of each type according to Mendelian genetics.

Round 0.1875 (green) 0.5625 (yellow)

Wrinkled 0.0625(green) 0.1875(yellow)

If one pea is drawn at random from the peas produced, what is the probability it is round?

If a simple random sample of 20 peas is drawn from those produced, what is the expected number of round peas?

If a simple random sample of 20 peas is drawn from those produced, what is the standard deviation of the number of round peas? (Round your answer to two decimal places.)

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...

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....

21.02 Gregor Mendel has been called the “father of genetics,” having formulated laws of inheritance even before the function of DNA was discovered. In one famous experiment with peas, he crossed pure breeds of plants producing smooth peas and plants producing wrinkled peas. The first-generation peas were all smooth. In the second generation (F2), he obtained 5474 smooth-pea plants and 1850 wrinkled-pea plants. Do these data agree with the conclusion that F2 is made up of 75% dominant trait (in...
