- Bolting is when a plant starts to spend its energy on producing flowers. Initial bolting time is figured by the number of days from germination to bolting. Rosette area is figured by the average rosette area of the plant at the time of bolting. Researchers created strains of A. thaliana to have varying somatic ploidy levels to study the resulting phenotypes. The graphs show how initial bolting time and rosette area relate to the number of chromosomes in each strain’s somatic cells. Which of the following best describes how a change in genotype affects the phenotype of A. thaliana? The largest average change in both phenotypes occurred from the 2n to the 4n strain. The largest average change in both phenotypes occurred from the 4n to the 6n strain. A lesser number of chromosomes results in plants with a later initial bolting time. A greater number of chromosomes results in plants that have larger rosettes areas.arrow_forwardWhat are chasmogamous flowers? Can cross-pollination occur in cleistogamous flowers?
