Question
Chapter 50, Problem 2ITD
Summary Introduction
To review:
Whether the most common defects in single-birth is more or less common in the multiple-birth group as per the given data.
Introduction:
A study on the birth defects in the single-birth and the multiple-birth group is made. This study tabulated the prevalence of various birth defects per 10,000 live births in Florida from 1996 to 2000. It was suggested to the families considering fertility treatments to be aware of the fact that multifetal pregnancy and multiple births increase the chances of birth defects.

Select one:
A. two eggs are fertilized by two sperm cells, resulting in a fraternal twin.
B. High levels of FSH stimulate the maturation of three ovums.
C. Two eggs are fertilized by one sperm cell, resulting in a monozygotic twin.
D. One egg is fertilized by one sperm but divides into two zygotes, resulting in two babies of the same gender.

The graph in the right hand column shows the incidence of Down syndrome in the offspring of normal parents as the age of the mother increases. For women under the age of 30, how many infants with Down syndrome are born per 1,000 births? How many for women at age 40? At age 50? How many times more likely is a 50-year-old woman to give birth to a baby with Down syndrome than a 30-year-old woman?

- Birth Defects and Multiple Births A woman who carries multiple offspring at the same time increases the risk of some birth defects. FIGURE 42.18 shows the results of Yiwei Tang's study of birth defects reported in Florida from 1W6 to 2000. Tang compared the incidence of various defects among single and multiple births. She calculated the relative risk for each type of defect based on type of birth, and corrected for other differences that might increase risk such as maternal age, income, race, and medical care during pregnancy. A relative risk of less than 1 means that multiple births pose less risk of that defect occurring. A relative risk greater than 1 means multiples are more likely to have a defect. FIGURE 42.18 Prevalence, per 10,000 live births, of various types of birth defects among multiple aria single births. Relative risk for each defect is given after researches adjusted for the motor's age, race, previous adverse pregnancy experience, education, Medicaid participation during pregnancy, as well as the infant's sex and number of siblings. 4.
