Textbook Question
Chapter 28, Problem 2DCR
If parents wish to know the sex of their unborn baby, they usually have to wait until weeks 18–22 of development before a sonogram determining the sex can be performed. Based upon your knowledge of reproductive system development, explain why the sex of the unborn baby can’t be determined easily before this time.

Students have asked these similar questions
Emily and her husband are thrilled as they peer into Emily's uterus by means of an ultrasound. The physician reports that the pregnancy appears normal and that their baby's organs, spine, and arms and legs are developing as expected. Given this information, the current stage of prenatal development is the
embryonic period germinal period zygotic period fetal stage placenta
Suppose that in the near future, you are a prenatal care provider. In the most recent ultrasound checkup on the expecting mother, you unfortunately found that the fetus is suffering a neural tube defect in the form of anencephaly. Seeing as the mother is still in the 12th week of pregnancy or the 1st trimester, the pregnancy can still be terminated via medical means. How would you explain to the parents the situation they are in?
Please discuss the physiology of labor until childbirth. Please include a flowchart to illustrate this.

Only the inner cell mass cells in a blastocyst are pluripotent. b. The trophoblast has an important role in maintaining the pregnancy, as it prevents the endometrium from shedding. c. As hCG takes over maintaining the endometrium immediately after implantation, the corpus luteum degenerates into the corpus albican. d. All 16 cells in a morula are truly totipotent, meaning that they can become any cells in the human body.arrow_forwardExplain Fetal Development by making any of these: charts, graphic organizers, tables, flowcharts, Venn diagrams, timelines, or T-charts.arrow_forward
- When doctors discuss prenatal development, they often calculate the due date from the first day of menstruation. In fact, the baby’s gestational age is calculated from the first day of menstruation. At a maternity clinic, an obstetrician mentions that when a woman is 10 weeks pregnant, the baby is referred to as a fetus. Which of the following is the correct calculation of the baby’s age from the moment of fertilization, assuming a 28-day ovarian cycle? Select one: a. The baby is 8 weeks old. This is when organ formation has completed. b. The baby is 12 weeks old and at the end of the first trimester. c. The baby is in its second trimester. This is when they are referred to as a fetus. d. The baby is 10 weeks old as stated by the doctor.arrow_forwardWhen doctors discuss prenatal development, they often calculate the due date from the first day of menstruation.

- Why would the absence of a father affect the timing of puberty?arrow_forwardDescribe the process of ovulation, the hormone involved and what is released into the Fallopian tube (It isn’t just the oocyte) . At what stage of meiosis is the secondary oocyte? What is the life expectancy of the secondary oocyte?arrow_forwardThere are 6 major events in fertilization. Discuss the process of fertilization or conception, with emphasis on the sperm-egg interaction. Proteins on the sperm plasma membrane bind to ZP3 molecules within the zona pellucida of the egg. Why is this event important? Zona binding triggers the acrosome reaction, in which the sperm plasma membrane fuses with the outer acrosomal membrane, causing exocytosis of acrosomal contents. What is in the "acrosomal content"? Acrosomal enzymes begin to dissolve a hole in the zona pellucida. This enzymatic degradation, accompanied by rapid sperm tail beating, moves the sperm through the zona. Where does the sperm intend to reach?arrow_forward
- Young married couple had been trying to conceive a baby for 2 years without success. The husband has a sperm count in the “fertile” range. The wife menstruates regularly. What biological and hormonal indicators could you use to determine whether the woman was ovulating?
