Hint:
Down syndrome is an inborn disorder that results in intellectual disabilities and characteristic facial features. There is a total of 46 chromosomes in humans. But babies with Down syndrome have one extra chromosome on the 21st chromosome, resulting in three copies of the chromosomes instead of two.
Complete step by step answer:
The symptoms of Down syndrome may be mild, moderate, or severe. Even though all people who have this disease may not show similar features some of the common characteristics of Down syndrome are as follows. Babies with Down syndrome may have mild to moderate cognitive disabilities. Kids with Down syndrome may face language delays and difficulties with memory.
Some other features of people with Down syndrome are poor muscle tone, small ears, protruding tongue, a short physique with short neck, slanted eyes which are diamond-shaped, small feet and hands, short fingers, a flattened face, and attention and sleep problems.
Option ‘B’ is correct
Additional Information:
People with Down syndrome always have intellectual or physical disabilities. Even though they are adults, their mental age is below nine years. They usually lack a healthy immune system and reach developmental milestones at a later age. They have an increased risk of several other health problems, such as epilepsy, congenital heart defect, thyroid diseases, mental disorders, and leukaemia.
Note:
In most cases, Down syndrome cannot be inherited. It is caused by an error in cell division during the early development of the fetus. Translocation Down syndrome can be inherited from parents to offspring.
