what happens in Dislexia, genetic or brain damage ?..

Answer / swapna

Dyslexia is an unexpected impairment in reading and
spelling despite a normal intellect.


Dyslexia results from a disfunction in visual memory and
visual perception due to a delayment in maturation. Most
dyslexics also display poor writing ability.


Dyslexia is a classical primary reading disorder and should
be differentiated from secondary disorders such as mental
retardation, educational or environmental deprivation, or
physical/organic diseases.


The disorder results as a combination of genetic and
environmental causes, which can induce variations in the
behavioral, cognitive, and physiological measures related
to reading disability. Dyslexia was previously called
congenital word blindness.

Consider two linked autosomal genes. The dominant allele C of the first gene causes cataracts of the eye, whereas its recessive allele produces normal eyes. The dominant allele P causes polydactyly (an extra finger) whereas its allele (p) produces a normal number of fingers. A man with cataracts and normal fingers marries a woman with polydactyly and normal eyes. Their son has both polydactyly and cataracts and he marries a woman with neither trait. What is the probability that their first child will have cataracts and polydactyly?
