Answer 2

Answer:

a) Klinefelter Syndrome

b) Down's Syndrome

Explanation:

• Klinefelter is a genetic defect in the sex chromosome. It is a condition that affects boys as the presence of an extra X-chromosome makes them infertile and involves the under-development of sexual characters.

• Symptoms and conditions vary among individuals.

• Down syndrome is a chromosomal condition in which an extra copy of Chromosome 21, may be a partial or a full extra copy.

• Down syndrome affects overall growth and mental development.

Even the slightest defect or change in the chromosome or chromosome number can affect the organism's development and can cause a genetic disorder or can lead to death.
