BLG1501 Assignment 2 (COMPLETE ANSWERS) Semester 2 2026 - DUE 19 September 2026. A purple flower (P) is dominant, and the white flower (p) is recessive. Use the Punnet square to predict the results of this monohybrid cross between a purple homozygote flower and a white homozygote flower and state the phenotypic and genotypic ratios of the F2 generation. Tabulate the differences between prokaryotic and eukaryotic cells. Write explanatory notes on the structure and function of ribosomes. List the phases of meiosis I and meiosis II and describe the events characteristic of each phase. Explain how enzyme activity can be regulated or controlled by environmental factors, substrate concentration, co-factors and enzyme inhibitors. Define Mendel’s law of independent assortment in your own words. In sesame plants, the one-pod condition is dominant to the three-pod condition. Normal leaf is dominant to wrinkled leaf. A homozygous plant with the one-pod condition and normal leaves is crossed with a homozygous plant with the three-pod condition and wrinkled leaves. Use a Punnett square to predict the phenotypic and genotypic ratios of the F2 generation. Distinguish between parasitism, mutualism, and commensalism and give examples of each symbiotic relationship Briefly explain the four major threats to biodiversity and give an example of each. 1 A purple flower (P) is dominant, and the white flower (p) is recessive.
