Fig. 121. Diploid and haploid peppers: (a) and (b), haploid ^nd diploid 

 plants; (c) and (d), stomata from haploid and diploid plants; (e), diakinesis 

 in a haploid showing twelve univalents; (/), diakinesis in a diploid, show- 

 ing twelve bivalents; ig), late diakinesis in the haploid with chromosomes 

 associating in pairs. Note that the haploid is generally smaller and has 

 smaller stomata and guard cells than the diploid. (Courtesy of Dr. R.
