Hint: Some chromosomal abnormalities occur due to the presence of an extra chromosome, while some abnormalities occur due to the deleted or duplicated chromosome, and these abnormalities may result in the development of syndromes.
Complete answer:
During cell division of normal cells, always the mitosis will take place and it in turn forms the diploid number of chromosomes as a daughter cells
In humans usually, there are two types of chromosomes, they are autosomes and Allosomes.
And the number of chromosomes per each cell consists of 46 chromosomes, out of the 44 are autosomes and two are Allosomes, based on the type of Allosomes present in the cells, gender classification of the body is determined
If a cell has 44 autosomes and 2 sex chromosomes which are XX then the resulted gender of the person is female, and at the same time after the cell division, if the resulted cells consist of XY chromosomes, then the resulted gender is male and it is also a wrong option for the given question
Any abnormality in cell division so that female born with a single X chromosome or 45X, then the condition is called as turner's syndrome,
Abnormalities in the development of reproductive organs and delay in puberty, etc.
So it is also wrong
The genetic condition, in which after the cell division, where male born with an extra X chromosome, which means 44+XXY
In this male’s breast develops and infertility is seen and the body has eunuchoid features, which mean tall and thin.
So from the above explanation, D) XXY is the correct answer.
Note:
Apart from the numerical chromosomal abnormalities, it also consists of structural abnormalities also, mostly risk of this chromosomal abnormalities seen in the people having family history and age of the women when she conceives, etc.
