Respuesta :
In mammals, is aneuploidy of the x chromosome more often viable than aneuploidy of the autosomes is only one X chromosome remains fully functional in mammalian cells.
Many or all genes on additional X chromosomes are silenced early during development.
Aneuploidy is the condition in which the chromosomes and the number of it are missing that is either one chromosome can be missed or more than one which can lead to abnormalities in the body and malfunctioning in the expression of characters and can also lead to any chromosome number that is not the exact multiple of haploid number which in humans is 23 and its paired form has 46 chromosomes so whenever there is a loss in one chromosomes or addition of one chromosome it can lead to different syndromes like down syndrome, knilfeltners syndrome, turners syndrome and many more and it can be the main cause of miscarriages during pregnancy as well and in mammals aneuploidy of x chromosome is more viable because only one X chromosome remains fully functional in mammalian cells.
Many or all genes on additional X chromosomes are silenced early during development. In females there are two x chromosomes so even the other is silenced the other one is functional and in the same way in males the x chromosomes remains functional that is why aneuploidy affects are seen on x chromosomes.
