Answer 1

Геномна мутація- анеуплюдія .
2n=21хромосома 
Може передати нащадкам,це веде до різноманітних вад розвитку,у тому числі розумової відсталості 

Answer 2

Chromosomal Mutation and Genetic Disorder

The chromosomal mutation described, where all cells of the affected woman have 45 chromosomes and one sex chromosome is missing, is known as Turner syndrome. This condition is characterized by the absence of all or part of one of the X chromosomes. The chromosomal makeup of a woman with Turner syndrome is typically 45,X. This means that she has 45 chromosomes in total, with only one sex chromosome, which is an X chromosome, instead of the usual XX in females [[1]].

Transmission of the Mutation

Turner syndrome is not typically inherited. It is usually caused by a random error in cell division during the formation of the egg or sperm. Therefore, a woman with Turner syndrome is unlikely to pass the condition to her offspring. However, in rare cases, it can be inherited if one of the parents has a chromosomal rearrangement [[2]].

In summary, the described chromosomal mutation is known as Turner syndrome, characterized by a chromosomal makeup of 45,X, and it is unlikely for the affected woman to pass this condition to her offspring.
