Cytogenetic study and pollen viability of three populations of Diplotaxis harra (Brassicaceae) in Iran [PDF]
Journal of Cell and Molecular Research, 2014 In this study, we examined the chromosome number, detailed male meiosis, microsporogenesis, pollen fertility and distribution of cytotypes of Diplotaxis harra (Forssk.) Boiss. This is the first cytogenetic report of the taxon.

Chromosome numbers in. Begonia. 2.
Netherlands Journal of Agricultural Science, 1969 The somatic chromosome numbers are presented of 90 Begonia spp. of African, Asian and American origin, including a few of those previously listed [see H.A., 40: 1600] whose nomenclature or chromosome numbers are reconsidered. Sixteen different numbers were found, ranging between 16 and 76.

Birth seasonality studies in a large Prader-Willi syndrome cohort. [PDF]
, 2019 Prader-Willi syndrome (PWS) is generally due to sporadic paternal deletions of the chromosome 15q11-q13 region followed by maternal disomy 15. Advanced maternal age is more commonly seen in those with maternal disomy 15. Environmental factors (e.g., drug

Problematic octaploid forms and a new chromosome number in the genus Achillea L., 2n = 126
Acta Societatis Botanicorum Poloniae, 2014 Among the offspring of a problematic form of Achillea sp., a 2n = 126 seedling which probably arose as the result of fusion of unreduced octo- and hexaploid gametes (72 + 54) was found along with seedlings having an octaploid chromosome number (2n = 72).
