A family case of fertile human 45,X,psu dic(15;Y) males [PDF]
, 2006 We report on a familial case including four male probands from three generations with a 45,X,psu dic(15;Y)(p11.2;q12) karyotype. 45,X is usually associated with a female phenotype and only rarely with maleness, due to translocation of small Y chromosomal

Recombination, chromosome number and eusociality in the Hymenoptera. [PDF]
J Evol Biol, 2015 Extraordinarily high rates of recombination have been observed in some eusocial species. The most popular explanation is that increased recombination increases genetic variation among workers, which in turn increases colony performance, for example by ...
