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?
The abdomen length (in millimeters) was measured in 15 maleDrosophila, and the following data were obtained: 1.9, 2.4, 2.1,2.0, 2.2, 2.4, 1.7, 1.8, 2.0, 2.0, 2.3, 2.1, 1.6, 2.3, and 2.2. Calculatethe mean, standard deviation, and variance for this population ofmale fruit flies.
The American alligators (Alligator mississippiensis) that survived the initial spill were found to have high concentrations of DDE in their tissues. Decades later, the alligators in the lake still have DDE in their tissues and their populations do not seem to have recovered to pre-spill conditions. Many juvenile male alligators have low levels of testosterone. • How would low levels of testosterone affect the American alligator population?• Based on your reading of the materials in this unit, how do environmental factors affect fertility in humans?
Female spotted sandpipers aggressively court males and, aftermating, leave the clutch of young for the male to incubate. Thissequence may be repeated several times with different males untilno available males remain, forcing the female to incubate her lastclutch. Which of the following terms best describes this behavior?(A) polygyny(B) polyandry(C) promiscuity(D) certainty of paternity
You want to breed turtles and choose to incubate turtle eggs at the highest temperature (36°C) in the recommended range (22-36°C). You then, unexpectedly, observe that only female turtles are produced . This leads you to ask the question: "Does incubation temperature affect a turtle's sex?" Formulate a hypothesis and shortly explain what steps you will follow to ensure that this question is answered in a scientific manner.
What is the name of the "law" described by the formula in (1) (where R is how related two individuals a and b are, B is the reproductive benefit to B and C is the reproductive cost to a? (1) RabBb > Ca
In some cases, males or females do care for young of their own species that are not their own, as when certain male fish take over and protect egg masses being brooded by other males or when female ducks acquire ducklings that have just left someone else’s nest. Propose alternative hypotheses to explain this phenomenon. Under what circumstances might adoptions actually raise the caregiver’s reproductive success? Under what other circumstances might adopters help nongenetic offspring as a cost of achieving some other goal? Don't write from any online source..
Should I try to rescue my sister who is drowning if there is a 75% chance that I will drown in the process? Assume that humans produce an average of 2 offspring in their lifetime. Remember that Hamilton’s rule is satisfied if rB>C. What is the value of C in this situation: What is the value of B in this situation: What is the value of r in this situation: Should I try to rescue my sibling? Yes or no
can you please explain this Below is a life table for a hypothetical organism. What is the expected lifetime reproductive success for individuals carrying the A1 allele? (Note: RS: reproductive success) Question 3 options: 2.35 2.50 2.64 3.66 24.00
Two human populations have the same net reproductive rates (R0), but different generationtimes. In what ways are these two populations similar and different?
After observing a finite population of asexually reproducing salamanders, which of the following outcomes is consistent with Müller’s ratchet? a. The population fitness will decline due to the least fit individuals randomly not surviving to produce offspring into the next generation. b. The population fitness will increase due to the most fit individuals randomly not surviving to produce offspring into the next generation. c. The population fitness will decline due to the most fit individuals randomly not surviving to produce offspring into the next generation. d. The population fitness will increase due to the least fit individuals randomly not surviving to produce offspring into the next generation.
As a hypothetical example, imagine that you were studying a population of Eastern Collared-Lizards (Crotaphytus collaris). The lizards laid 2000 eggs, of which 1000 were eaten by raccoons and skunks. Eight hundred of the surviving juveniles were eaten by foxes and cats. One hundred and eighty of the young adults died during their first hibernation period. What is the indispensable mortality for each stage? If you want to increase the numbers of reproducing adults, which stage should you focus on?
