How do I calculate the P value? TSeed capsules of the Shepherd's pusse are either triangular or ovid. A cross blu a pure breeding plant withOvoid seed capsules and a pure breeding plant with triangular seed Capsules viewed Fl hybrids that all have triangularseed capsules. The Fl hybrid self-cross produced 50 F2 plants, 72 of which had triangular seed Capsules and 8of which had ovoid Seed Capswer You state your null hypothesis as follows: There is no significant differenblw the observed data and the expected ratio of 3:1 that would be predicted for a monohybrid cross.Any deviation abserved is simply due to random chance.a) Expected Ratio: 3:1 Fractions: 3/4 ib)Phena typic ClassObserved # Expected #72880TriangularOvaidTotalExpected Triangular:Expected Ovoid :80 × 3/4 = 6080 x 1/4= 20Triangular: (72-60)²( 60 )Ovoid: (8-20)2 = 7.2(20)d) P-valueP-value: 0.00194577= 2.4602080P<0.05= reject the null hypothesP>0.05 fail to reject1/4(0-E)/E2.47. 2x² = 9.6Total = 2.4+7.2c) Degrees of Freedom :Degrees of = (# of phenotypic class - 1) = (2-1) = 1Freedom5 Nitrogenous Bases > U, T, C, A, G= 9.6 Chi square vakeWhat is a P-valve = the probability that we would see the degree of deviation observed heregiven that the null hypothesis is true.

This image shows the offspring that result from a dihybrid cross between a plant with wrinkled green seeds and a plant with round yellow seeds. Generation Generation 2 round, yellow wrinkled, yel wrled green How can this graphic be used to support the idea of independent assortment? O The fact that the seeds can be one of two different colors shows that the chromosomes with the seed color gene must sort independently. O The fact that the seeds can be one of two different textures shows that the chrorhosomes with the seed texture gene must sort independently. O The idea that alleles sort independently is supported by the fact that some second generation offspring have trait combinations that the first generation parents do not have. O The idea that alleles sort independently is supported by the fact that some second generation offspring have the same trait combinations that the first generation parents have. https://student.masteryconnect.com/?iv=it4119tzPsQ…
A strain of plants has a mean height of 24 cm. A second strain ofthe same species from a different geographical region also has a mean height of 24 cm. When plants from the two strains arecrossed together, the F1 plants are the same height as the parentplants. However, the F2 generation shows a wide range ofheights; the majority are like the P1 and F1 plants, but approximately4 of 1000 are only 12 cm high, and about 4 of 1000 are36 cm high. Question: What mode of inheritance is occurring here?
Figure 8.9 In pea plants, round peas (R) are dominant to wrinkled peas (r). You do a test cross between a pea plant with wrinkled peas (genotype rr) and a plant of unknown genotype that has round peas. You end up with three plants, all which have round peas. From this data, can you tell if the parent plant is homozygous dominant or heterozygous?
Figure 8.10 In pea plants, purple flowers (P) are dominant to white (p), and yellow peas (Y) are dominant to green (y). What are the possible genotypes and phenotypes for a cross between PpYY and ppYy pea plants? How many squares would you need to complete a Punnett square analysis of this cross?
More Crosses with Pea Plants: The Principle of Independent Assortment Consider the following cross in pea plants, in which smooth pea shape is dominant to wrinkled, and yellow pea color is dominant to green. A plant with smooth yellow peas is crossed to a plant with wrinkled green peas. The offspring produced peas that were all smooth and yellow. What are the genotypes of the parents? What are the genotypes of the offspring?
More Crosses with Pea Plants: The Principle of Independent Assortment Determine the possible genotypes of the following parents by analyzing the phenotypes of their children. In this case, we will assume that brown eyes (B) is dominant to blue (b) and that right-handedness (R) is dominant to left-handedness (r). a. Parents: brown eyes, right-handed brown eyes, right-handed Offspring: 3/4 brown eyes, right-handed 1/4 blue eyes, right-handed b. Parents: brown eyes, right-handed blue eyes, right-handed Offspring: 6/16 blue eyes, right-handed 2/16 blue eyes, left-handed 6/16 brown eyes, right-handed 2/16 brown eyes, left-handed c.

More Crosses with Pea Plants: The Principle of Independent Assortment In pea plants, long stems are dominant to short stems, purple flowers are dominant to white, and round peas are dominant to wrinkled. Each trait is determined by a single, different gene. A plant that is heterozygous at all three loci is self-crossed, and 2,048 progeny are examined. How many of these plants would you expect to be long stemmed with purple flowers, producing wrinkled peas?
