- 2. The endosperm of maize can either be yellow or white. This endosperm color is governed by a gene with two alleles, Y has yellow endosperm and y has white endosperm. However, this endosperm color is masked when the aleurone is colored purple. A true-breeding maize line with the color inhibitor and yellow endosperm (C'C'YY) (so they were yellow) was crossed to a true-breeding line with purple aleurone (and white endosperm) (CCyy). The F1 were crossed and you have been given the results of this cross. What is your proposed phenotypic and genotypic ratio for the offspring (kernels) of this cross? Perform a Chi-square to prove or disprove this ratio.3. A farmer received a purchase order to supply hundreds of carnations for an event that will be held in two months'. As a horticulturist, you suggested the farmer to control the photoperiod to make sure that he could produce the number of carnations needed in time. By using your own words, explain the concept of photoperiodism and its types. Include examples of plants for each type. In your opinion, are plants in the tropical rainforests of Malaysia photoperiodic? State your justifications. [10 marks]1.
