Chapter 42, Problem 3DAA
Summary Introduction
To explain: The type of defect that is more than twice the risk to occur in the multiple-births than in single newborns.
Concept introduction: During the gestation period, the mother can have a single birth or multiple births. A single birth is one in which only one fetus is carried during the gestation period in the womb. A multiple birth is one in which more than one fetus is carried during the gestation period such as twins, triplets, quadruplets, and so on. Carrying more than one fetus in the womb results in the insufficient supply of nutrients to the developing fetus. These fetuses become still-born or born with abnormalities.

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?
What are the three (3) leading causes of infant mortality
For each leading cause, suggest two (2) or more public health measures aimed at reducing the risk.

- 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. Does a multiple pregnancy increase the relative risk of chromosomal defects in offspring?arrow_forwardReproductive modes can be defined based on energetic provisioning (lechithotrophy vs. matritrophy) or birth style (ovipary vs. vivipary). Reproductive modes related to birth style mostly fall into clear categories of energetic provisioning. Define the above four reproductive modes based on energetics and style that make them distinct. Be sure to mention WHEN the relevant events related to each occur. Finally, explain why the birth style of ovovivipary less clearly falls into any one of these categories...arrow_forwardWhat are the causes of global maternal and infant mortality and explain the relationship of skilled birth attendants, cleanliness at delivery, and better birth outcomes.arrow_forward

Refer to the following diagram which shows different stages of embryonic and foetal development in a number of different organisms. In the earlier stages of the embryonic development, the similarities between the organisms are greater than later in the development process. In the organisms shown, all the organisms develop from a fertilised egg cell. For these organisms to develop into functional offspring of that species, which one of the following statements must be correct? Accessibility: Investigate $ 4 J. Specific genes in each organism are turned on and/or off to enable cells to differentiate and express species specific characteristics K. All the organisms have the same genes and it is differential gene expression that determines the characteristics that will develop. L.
