Chromosome+Abnormalities

=Summary=

Most chromosomal abnormalities occur during meiosis when parts of two different chromosomes become attached, or during duplication when the cells don’t divide properly. 1 in every 200 babies are born with obvious chromosome abnormalities. Half of these cases involve the 22 autosomes, and the other half involves the sex chromosomes. The most common chromosomal abnormality is Down syndrome Down syndrome is when an individual is born with 47 chromosomes instead of 46. The extra chromosome is located on the 21st pair. Down’s can be related to the mother's age as ,once a women reaches 35 years of age, the chances of her giving birth to a down syndrome child increases substantially. For women 45 an older, the chance of giving birth to a Down syndrome child is 1 in 25. Turner syndrome affects the sex chromosomes. It occurs once in every 2500 births and can't be linked to the mother's age nor does it run in families. It only occurs in females and is defined be the absence of the second x chromosome. The traits of Turner syndrome women include poor spatial ability and directional sense. Over time people with Turner syndrome have come to be aided by hormone treatment.
