Diploid (2n) organisms that reproduce sexually produce haploid (n) gametes. Some plants, such as wheat, can produce diploid or haploid gametes. These gametes can fertilise other diploid or haploid gametes. Which statements are correct for plants like these? 1 Diploid gametes may be produced by a fault in the reduction division (meiosis). 2 The offspring will always show an increased chromosome number. 3 The offspring could be either 2n, 3n or 4n. 4 The chromosome number could, in theory, increase with each generation.
