information is learned as a result of this ultrasound test? Be specific. * An ultrasound is a machine that uses sound waves to produce an image of the unborn baby for analysis. * The baby is in the breech position, which means that butt is facing down and usually 95% of the time the baby will turn around closer to birth. * Dr. Cohen identified the placenta which feeds the baby oxygen and nutrients. He also identified the cerebellum which is hotdog shaped and is very important. If the cerebellum

or the genetics that are passed down. The interaction of genes from the mother and genes from the father affects the embryo’s growth in many ways (Berger, 2012). Genetics can vary many different developmental stages starting with the embryo. One instance of this is the deciding factor of gender for the baby depends on which chromosome (x or y) was passed from the father. Another instance of how genetics can affect development is with Down syndrome. “Down syndrome is a set of physical and mental

when hospital staff told them their daughter looked as though she had Down syndrome. A doctor asked Deborah if she’d had a prenatal test – a chorionic villus sampling (CVS) – and Levy said yes, because she was 34, she and her husband were concerned about the possibility of genetic disorders. A first-trimester screening showed Deborah’s chances were estimated to be higher than average for giving birth to a child with Down syndrome, at about 1 in 130. So when Deborah was 13 weeks pregnant, she underwent

I have done my report on trisomy 21. This disease was later named Down Syndrome. In 1866 a doctor named John Langdon Down first saw some children that were similar to some other mentally retarded children. He had no idea what this disease was, but was the first person to study it. As time went on medicine became more advanced. In 1959 a French doctor named Jerome Legeune saw people who had this unknown disease, and that they had 47 chromosomes instead of 46 chromosomes. This disease was then

Kimberly Douglas Dec 3 2014 Genetics Down Syndrome Down syndrome (DS) or Trisomy 21 is a complex developmental genetic disorder in which a person has 47 chromosomes instead of 46. Normally, a fertilized egg has 23 pairs of chromosomes. But in most cases, people living with Down syndrome have an extra copy of chromosome 21 also known as Trisomy 21, which is responsible for 95% Down syndrome cases and most common genetic cause of human mental retardation, with an incidence of 1-600/1-1000
