Not a problem from a reproductive standpoint or from a morphological standpoint but those with the XXX or with XXX mosaic syndrome who have intellectual developmental issues may beg to differ. Issues are not nearly as profound for XXX trisomy as for their XXY male counterparts. The effects of trisomy can vary considerably from person to person.
yes they can, males and females can inherit up to 3 extra sex chromosomes possibly bringing their total count up to even 49 chromosomes.
a human man has two pairs of 23 chromosomes, in total 46. there are cases where there is an extra chromosome in the 23rd spot of chromosomes in this case the man will have an extra chromosome, this is the cause of syndrome of down.
Poly X females have an extra X chromosome, resulting from nondisjunction during meiosis in one of the parents. This leads to the presence of three X chromosomes (XXX) instead of the typical two. This extra chromosome can result in physical and cognitive differences in affected individuals.
Cells have 42 chromosomes, reproductive cells have 21. An extra chromosome is usually the cause of genetic defects.

Females carry two X chromosomes. One is inherited from each parent. Both of the X chromosomes do not have to be activated. One of the X chromosomes is neutralized. However, the extra X chromosome can be reactivated in some cases. This does not means that females need only one chromosome. Females with only one X chromosome have genetic conditions that can cause disabilities such as Turner Syndrome.
Poly X females have an extra X chromosome, resulting from nondisjunction during meiosis in one of the parents. This leads to the presence of three X chromosomes (XXX) instead of the typical two. This extra chromosome can result in physical and cognitive differences in affected individuals.
dyslexia is a disorder of the brain not a chromosome problem.
Cells have 42 chromosomes, reproductive cells have 21. An extra chromosome is usually the cause of genetic defects.
An individual with Down Syndrome has the presence of all or part of an extra 21st chromosome.
The effects of genotypes with extra X chromosomes (e.g., XXX) are often less severe because of X inactivation, where one of the X chromosomes is randomly inactivated in each cell of the body. This helps balance gene expression between males (XY) and females (XX), reducing the impact of having extra X chromosomes. In contrast, in other trisomies (e.g., trisomy 21), the presence of an extra chromosome leads to a greater imbalance of gene expression, resulting in more severe effects.
No, Down syndrome is caused by nondisjunction resulting in an extra chromosome in the 21st pair. An inactivated X chromosome (Barr body) is normal for all females. Females inherit two X chromosomes, and one is heavily methylated.
Individuals with Klinefelter syndrome have an extra X chromosome (XXY), resulting in the presence of both X and Y chromosomes. This genetic condition can lead to a variety of symptoms, such as reduced fertility and developmental delays.

Trisomy X aka "Triple X syndrome" is a disorder that affects females and is characterized by the presence of an additional X chromosome. Normally, females have two X chromosomes; however, females with trisomy X carry three X chromosomes in the nuclei of body cells. To be male requires a Y chomosome - which those with Trisomy X obviously lack.Trisomy refers to having an extra chromosome - 3 (tri-) instead of 2.Other types of gender related trisomy include:XXY Trisomy (Klinefelter syndrome) where males have an extra X chromosomeXYY Trisomy (or simply XYY karotype) is where males have an extra Y chromosome.
