A P. guajava karyogram showing 2n = 2x = 22 chromosomes, being five metacentric (3, 4, 8, 9, 10) and six submetacentric pairs (1, 2, 5, 6, 7, 11) B P. guineense karyogram showing 2n = 4x = 44 chromosomes, with two metacentric (11, 12) and twenty submetacentric pairs (1–10, 13–22). Note groups of morphologically identical chromosomes, such as 1 and 2, 3 and 4, 21 and 22. Bar = 5 μm.
