and dogs accordingly have a lower rate of monosomy x than observed in other species; however, a large pseudoautosomal region is not considered a contraindication for trisomy x, and canine trisomy x may have a comparable prevalence to the human form. trisomy x is also observed in cattle, where it corresponds to a 61,xxx karyotype. a survey of 71 heifers who failed to become pregnant after two breeding seasons found two cases of trisomy x. as of 2021 a total of eight heifers with trisomy x have been identified, seven of them were infertile. the condition also affect the river buffalo where the three known cases were sterile. notes 'karyotype' as a term has multiple meanings, all of which are used here. it may refer to a person's chromosome complement, to the test used to discern said chromosome complement, or to an image of chromosomes ascertained via such a test. aneuploidy is the presence of too many or too few chromosomes in a cell. as comparison, the average adult height for women in the anglosphere is around 162 cm (5 ft 4 in). male phenotypes, innate or induced, with forms of x chromosome polysomy that are usually phenotypically female do occur. for trisomy x, a trans man and several men with sex reversal have been recorded.
