what are the chances of a child getting downs syndrome?
441562
Statistics\n\n* Down syndrome occurs in roughly 1 of every 750 births in the United States.\n* The risk of having a child with Down syndrome is less than 1 in 2,500 among young women.\n* This risk increases to roughly 1 in 350 when women reach 35 years of age.\n* After age 45, the risk of having a child with Down Syndrome is about 1 in 25.

I know of a family that had 4 kids......they were first cousins, and they ended up having 4 kids with learning disabilities....and downs syndrome......\n\nSo I would say no...do not have kids unless you are prepared to have kids with many challenges.....

Almost all males are infertile, but fertility in females is possible. About half of females are fertile. \n\nSo yes, it's possible, but it's not exactly common. More are infertile than fertile.\n\nIt's not really clear why most males are sterile, but I would suggest that the trisomy 21 condition (people with Down's syndrome have an extra 21st chromosome - in most cases, anyway) somehow interferes with the inactivation of the X chromosome in males, which leads to infertility.

high blood pressure, decreased fertility, heart disease, asthma, lung disease, emphysema, chronic pneumonia, various cancers, etc.\nWomen are likely to have babies that are low birthweight also.

If both parents are RH postive, the child will also be RH positive. There is no chance of RH negativity unless at least 1 parent is negative.

Its just genetics..... out of six of us kids 4 have it.... if its bad you can get a shoe !!!

Genetic defects can occur randomly, but the mother getting sick or having an unhealthly lifestyle during pregnacy could also cause birth defects like deafness.

I've read the chances are anywhere from 10% to 22%.  \n\n(there are 3 children in my family.  I'm straight. My siblings are gay)

it is a genetic disorder caused by having 3 chromosome #18s instead of 2. this is called trisomy 18. (down sydrome is caused by trisomy 21). \n\nover 90% of these babies have major heart defects. more than half are deaf. they require very intense care at birth, have a high risk of dying, and have major medical and developmental problems if they survive.

Down's syndrome is a genetic disorder that was \nestablished at the moment of conception. Normally, there are 23 pairs of\nchromosomes that make up the fertilized egg. One of each pair is from\nthe sperm and the other from the egg. In Down's there is an extra \nchromosome 21. The medical term is trisomy 21. This is the usual reason\nfor Down's syndrome. \n\nThe most obvious consequences of having an extra chromosome 21 are \nan epicanthal fold around the eyes, short stature, dental deformities,\nbroad chest and mental retardation. The epicanthal fold about the eyes \ngive them an Asiatic or Mongolian appearance, hence, the older term\nmongoloid.

Actually, the odds are not 50:50.  The chances are 51.4 male to 48.6 female.  So the odds are slighly in favor of a boy.\n\nhttp://www.ourstolenfuture.org/NewScience/reproduction/sexratio/sexratio.htm\n\nAs people have said, the births are not connected so outcome of each event is independent.  So each birth event would seem to have the same likelihood as any other birth event.\n\nHowever, there may be individual factors which are not accounted for in this study.  We have several friends who have all girls.  3 girls in one family, 4 in another. While statistically plausible, and I haven't found any specific studies on this, I'm betting that there are heredity and environmental factors that are involved. Certainly their's some interest in why the birth rates of certain countries deviate significantly from the norm.\n\nHere's another website that talks about ways of modifying your behavior that might increase the odds of a boy or a girl.  It's not scientific but in the quote: "Dr. Moore also notes in his book that selecting a child's gender shouldn?t be taken too seriously, but he thinks using his methods make trying that much more fun."\n\nhttp://preconception.com/resources/articles/tochance.htm\n\nOf course, if you choose to adopt and make a proactive choice of gender (boy or girl), you have a much strongest choice of influencing the odds.

Genetic predisposition among other things.

I don't know.  All I know is that a chance is just that, a chance.  It does not mean that your baby has Down's... I have heard of mothers that had perfectly healthy babies after being told there was something "wrong."  Good luck to you and your little one.

Many many causes, the most common are:\n\n-Usually the mums that give birth to babies with Down syndrome are more that 40 years old.\n-Mums taking drugs or alcohol during pregnancy\n-Accidents or diseases during pregnancy\n-Genetic conditions

depends on how the gene pool shakes out for the child.

Different disorders.  My sister is mentally chalenged and i have found that the the kids that are worse, usually look a little different.  This can be caused by many different problems in birth.  Others are the result of down syndrome.  It is the same as a mentally stable person that doesn't look "normal".

Yes, if they both have a blue ressesive gene in each one of their genetics. If this is the case, there is about a 1 in 4 chance of having a blue eyes baby. Of course, many babies are born with blue eyes and their eyes darker within days.
