Humans are diploid (2n), but many animals and plants are not. Weirdly enough, many domesticated crop plants are thought to have originated when two different species of plants with different ploidies were crossed. If I successfully crossed an octoploid (8n) plant with a diploid (10n) plant, what would the resulting ploidy of the offspring be

Imagine a self-reactive t cell that has not undergone clonal deletion in the thymus (that is to say, it has escaped central tolerance). if it encounters self antigen in the absence of an infection or inflammation, what will happen to this self-reactive t cell? (select two answers) (a) the t cell undergoes clonal expansion. (b) the t cell gains effector functions. (c) the t cell undergoes apoptosis. (d) the t cell becomes activated. (e) the t cell becomes anergic.
