How many chromosomes does a mentally retarded human have?

Answer 1

Humans typically have 46 chromosomes, arranged in 23 pairs, regardless of cognitive ability. Mental retardation, now often referred to as intellectual disability, can be caused by various genetic or environmental factors but does not change the standard chromosome number. Some genetic disorders associated with intellectual disabilities, like Down syndrome, involve an atypical number of chromosomes, but the general human chromosome count remains the same.
