You cross true-breeding purple and white flowered pea plants. All 202 of the F1 offspring are white. Next you conduct an F1 self cross and yield 312 white and 108 purple F2 offspring. (a) Based on the data, which trait is dominant? (b) Diagram the P and F1 crosses and show F2 offspring. Use symbols of your choice to show each genotype and phenotype. (c) Based on a Chi-Square hypothesis test, do the F2 results fit with what you expect?...

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...

Let's say you have a pea plant that has the dominant traits for Tall stalks and Yellow seeds (TY). You want to know if this plant is homozygous for these traits, or heterozygous. What would you cross it with, and what is this called? A Monohybrid cross: TY X TY a plant with the same phenotype B. Dihybrid cross: a plant with a different trait (pink flowers and tall stalks) C. Test-cross; a plant homozygous for the recessive alleles: short...
