- The gray mouse lemur (Microcebus murinus) is a species in which females come into estrus and mate with several males on one night each year. Females accept any and all partners, but a genetic analysis of offspring indicated a greater difference in the MHC genes of mothers and actual fathers than in mothers and males selected at random from the population (Schwensow et al. 2008). Use these results to evaluate the various hypotheses on the indirect genetic benefits of polyandry. What do they suggest about the mechanism that enables a sexually promiscuous female mammal to exercise mate choice? Don't write from any online source..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.Enumerate and give at least 5 unique mechanisms employed by organisms in order to determine the sex of the offspring. In each case, give an example of a species which represent such a scheme of producing sex(y) descendants. Put reference Mechanism Example 1 2 3 4 5 What evolutionary forces drive the turnover of these sex determination mechanisms?
- Because the reproductive success of female Hanuman langurs (Semnopithecus entellus) is almost certainly lowered when a newly installed male kills their young infants, selection should favor countermeasures against infanticidal males. In this light, why might already pregnant females mate with a new male soon after a takeover even though they are not ovulating? What significance do you attach to the discovery that when mares are impregnated by stallions at stables away from their home locations, they will also copulate repeatedly with the males in their home stables upon their return?Which of the following is a correct assumption based on scientific findings? a. Neandertal mothers and human fathers might have produced viable offspring. b. mDNA could be passed only from Neandertal father to child. c. Neandertal fathers and human mothers might have produced viable offspring. d. mDNA could be passed only from human father to child.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?
- Which of the following scenarios does NOT describe an event that leads to the conceptions of twins? 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.How do contraceptive methods such as vasectomy and tubal ligation help solve societal problems like overpopulation in the present times? How did it transform Philippine society in modern times?1. DAY 1 (Gestational)- stage:____________ event:_________________________2.

- Why did Galton modify the quincunx? a. Because the distribution of a trait (e.g., height) in offspring is more widespread than that of their parents. b. Because the distribution of a trait (e.g., height) in offspring has a higher mean relative to that of their parents. c. Because the distribution of a trait (e.g., height) in offspring is less widespread than that of their parents. d. Because the distribution of a trait (e.g., height) in offspring remains constant relative to that of their parents.Bateman (1948) and Trivers (1972) came to the conclusion that sexual selection is typically a more potent evolutionary mechanism in males than females because typically… a. Females are likely to combat each other for mates b. Male limitations to reproductive success is gamete production c. Males typically participate in more parental care than females d. Females invest substantially more energy than males in gamete150 patients with Crohn’s disease are given an experimental treatment in which they all drink “cocktails” containing thousands of pinworm eggs. Within one week, 72% of the patients report a reduction in their abdominal pain. Fill in the following table. Is there a control treatment (and, if so, what is it)? Is there any accounting for individual variation? Is there repetition in the experiment? What, if any, confounding variables are not addressed in the experiment? Can we say with some confidence that ingesting pinworm eggs is an effective treatment for the symptoms of Crohn’s disease?
