A peony plant with red petals was crossed with another plant having streaky petals. A geneticist states that 70% of the offspring resulting from this cross will have red flowers. To test this, 80 seeds from this cross were collected and germinated and 46 plants had red petals.

(a) Is there sufficient evidence at the 0.02 significance level to indicate the proportion of the hybrid plants with red petals differs from 70%? Use the P-value method in your test.

(b) What would a Type I error be in this case?

A peony plant with red petals was crossed with another plant having streaky petals. A geneticist states that 80% of the offspring resulting from this cross will have red petals. But based on your experience, less than 80% of the offspring will have red petals. So, to verify whether the geneticist claim is true or not, you want to test the null hypothesis Ho: u = 0.80 by computing the test statistics. You collected and germinated 120 seeds from this...

Mendel crossed a pure breeding tall pea plant having red flowers with a pure breeding short pea plant having white flowers. All the F1 plants were tall with red flowers. He then selfed the F1 plants and the F2 plants had new combination of traits. Using a punnet square, show the phenotypes and genotypes of the F2 plants.

A plant breeder crossed a red flowered hibiscus plant with a yellow flowered hibiscus, and all of the offspring had orange flowers. a) Of what type of inheritance is this an example? Provide the genotypes of the parents. He then allowed the orange-flowered plants to self-fertilize. b) Create a Punnett square and predict the genotypes AND phenotypes of the offspring from the orange-flowered plants.

Part III: Non-Mendelian Genetics 1.   In four-o’clock flowers red petals are incompletely dominant over white petals, producing pink petal flowers in the heterozygous stage. What would be the probability of having white offspring if two pink flowered plants were crossed? 2.   In humans, there are three alleles for blood types, A = IA, B = IB, and O = i. Type A and B are co-dominant alleles and type O is recessive. Could a man with type AB blood be...
