| Phenotype | O | E | O - E | (O -E)^2 | (O - E)^2/E |
|---|---|---|---|---|---|
| Green pods | 300 | 282 | 18 | 324 | 1.15 |
| Constricted green pods | 85 | 94 | -9 | 81 | 0.86 |
| Full yellow pods | 80 | 94 | -14 | 196 | 2.09 |
| Constricted yellow pods | 35 | 31 | 4 | 16 | 0.52 |
| Total | 4.62 |
The chi square value is the summation of (O-E)^2/E which is approximately 4.5 as calculated from the table (option 2).
4) If p value is more than 0.05, null hypothesis should not be rejected. So, in p values of 0.5 and 0.1, hypothesis should not be rejected.

98 Mendelian Genetics Exercise D: Mendel's Dihybrid Cross But wait there's morel Mender's monohybrid crosses established that inheritance of phenotypes happened by the interactions of discrete particles' (we now call alleles). Further, he discovered that those alleles segregate during the process of meiosis in the production of gametes, which recombine during fertilization. The result of these two insights can easily be predicted by a technique developed by R. C. Punnett. Once these principles were established, Mendel sought to understand how...

1 pts Question 4 In one of Mendel's dihybrid crosses of peas, he observed round yellow, round green, wrinkled yellow, and wrinkled green F2 plants. He used the Chi Square test to see if the number of plants he observed in each category matched the expected 9:3:3:1 ratio. The Chi Square value he calculated...

Two true breeding strains of peas, one with yellow and round seeds and the other with green and wrinkled seeds, were crossed. All the F1plants had yellow and round seeds. When these F1 plants were test crossed to the green and wrinkled parental strain, the following offspring were obtained: 30 yellow and round; 20 green and round; 26 yellow and wrinkled; 28 green and wrinkled. A) Please diagram the crosses described above, showing genotypes for each plant, using your own...

Question 5 of 11 O Attempt4 Gregor Mendel has been called the "father of genctics," having formulated laws of inheritance even before the function of DNA was discovered. In one famous experiment with peas, he crossed pure breeds of tall and dwarf pea plants. The first generation peas were all tall. In the second gencration (F2), he obtaincd 787 tall plants and 277 dwarf plants. Mendel's first law of inheritance is a nodel with a donínant and recessive rhenolype. The...

QUESTION 3 A test cross is set up to establish the genotype of a plant with rounded peas. It is crossed with a plant that is homozygous for wrinkled peas. A round pea shape is dominant over the wrinkled shape. The offspring derived in the test cross exhibit a 50:50 ratio of wrinkled and round peas. What is the genotype of the parent in question? Homozygous for round pea shape. Heterozygous for pea shape. Homozygous for wrinkled pea shape. Heterozygous...

1. Wild type blue-eyed mary has blue flowers. Two genes control the pathway that makes the blue pigment: The product of gene W turns a white precursor into magenta pigment. The product of gene M turns the magenta pigment into blue pigment. Each gene has a recessive loss-of-function allele: w and m, respectively. A double heterozygote (Ww Mm) is self-pollinated. What proportion...
