Summary Introduction
To determine:
The concept behind the provision of education for Down syndrome people.
The genetic disorders can be treated by education or not.
Introduction:
Down syndrome, also termed as trisomy 21, is a genetic disorder caused by the presence of third copy of chromosome 21. People suffering from this disease have retardation in growth, less thinking ability, and characteristic facial features. It is believed that the extra chromosome occurs by chance and is not affected by environmental factors.

A couple contemplating a pregnancy are in today for an appointment at a genetic counselling clinic to identify and interpret their risk of an inherited disorder. The nurse explains during teaching that all the following are characteristic features of fragile X chromosome of a 3-year-old male child EXCEPT:
a. Macroorchidism
b. Autistic behavior
c. Intellectual disability
d. Characteristic facial features
e. Hyperextensible finger joints
Imagine that you are in your late 30s or early 40s and decide that you want a child.
You realize that you’re at greater risk of having a child with Down’s Syndrome.
What sorts of genetic screening are available today? If you find out that this child has
this condition, do you think it’s appropriate to have an abortion? Why or why not?
Question: Does elective abortion of fetuses with physical or other developmental disabilities
have an effect on the perception of personhood, dignity, and rights in society?
Explain.
What is the probability that they will have a baby boy with brown eyes and cleft chin
Parents Genotype :
Bb/bb – Eye Color - (brown eyes dominant , blue eyes recessive)
Dd- Dimples ( dominant)
Cc/cc- Cleft chin (Dominant)

- At her first prenatal visit, a woman relates that her maternal aunt has cystic fibrosis, an autosomal recessive illness. Which of the following statements is appropriate for the nurse to make? a. It is unnecessary for you to worry since our aunt is not a direct relation." b. "We can check to see whether or not you are a carrier for cystic fibrosis." c. "You should have an amniocentesis to see whether or not your child has the disease." d. Please ask your mother whether she has ever had any symptoms of cystic fibrosisarrow_forwardCreate a hypothetical person and situation as a real life example to illustrate your position. Who is this person? How old is this person? What chromosomal abnormalities does this person have? How does genetic testing and counseling make this person’s life better or worse? Ultimately, should your hypothetical person seek genetic counseling?arrow_forwardAlex is newly pregnant with twins and curious about everything about her developing children. Her doctor was able to tell her that her twins are dizygotic twins via ultrasound. In your essay, describe the difference between monozygotic and dizygotic twins and explain how each is conceived. Alex is also wondering about the genetics of her children and how they will act when they are older. Offer an explanation of genotype and phenotype and provide an example of each specific to Alex’s future children being dizygotic twins. Finally, in your previous explanation be sure to also describe how most traits are both polygenic and multifactorial and how that may influence her twins’ phenotypes.arrow_forward

- Gaucher disease is an early onset rare autosomal recessively inherited lysosomal storage disorder (LSD). An adult woman who has no symptoms but has two affected brothers is referred for genetic counselling. Which of the following is correct? Oa. Before any carrier testing is carried out the woman can be correctly informed that the probability that her first son will be affected is 1 in 4. b. With two affected brothers the probability of her being a carrier is 1. Oc. If she is a carrier then the probability that each of her sons and each of her daughters will be affected is 1 in 4. d. The probability that she is a carrier is 1/2 Oe. The probability that she is a carrier is 2/3.arrow_forwardColor blindness is an X-linked recessive disease.
