What is meiosis in sexual reproduction?

Gametes or sex cells, which are needed for sexual reproduction are created during meiosis.

It deactivates the sporophytic information while activating the genetic information for the production of sex cells.

Meiosis is a kind of cell division that results in the production of four gamete cells and a 50% reduction in the number of chromosomes in the parent cell. To develop egg and sperm cells for sexual reproduction, this procedure is necessary.

Therefore in sexually reproducing organisms meiosis is important to produce gametes, hence option a is correct.

What are the different types of chromosomal abnormalities?

Chromosomal abnormalities are of different types; some are related to autosomes, and some are related to X and Y chromosomes. The down syndrome happens due to the trisomy in the 21st chromosome, which means instead of two chromosomes, there are three chromosomes.

In Patau syndrome, the trisomy is seen in the 13th pair of homologous chromosomes, and as a result, instead of two chromosomes, three are present. Klinefelter syndrome is associated with males who have an extra X chromosome. Infertility is observed as a result of this male display of female characteristics, such as behavioral changes. Turner syndrome is associated with females who have lost one X chromosome.

As a result, the correct answer is option D, which is Klinefelter syndrome, which is XXY.
