4. Adult human females carry gametes arrested in Meiosis I. True or false?
answer. False because before puberty female gametes arrested in Meiosis 1 but when they attain puberty [adult] the Meiosis starts again and it also arrested in meiosis 2 until a sperm does not meet it. when sperm meet it then female gamete continue meiosis and fertilization occurs.
4. Adult human females carry gametes arrested in Meiosis I. True or false?
The end result of meiosis in human females is ______. A. one egg and 4 polar bodies B. three haploid cells C. four diploid cells D. four eggs E. none of the answers are correct
At the end of meiosis, for each primary spermatocyte, how many functional gametes do human males produce?
8. Suppose a primary oocyte undergoes nondisjuction during meiosis I. If the resulting gametes are crossed with normal sperm. What would be the frequency of males to females expected? a. 1 female : 1 male b. 2 females : 1 male c. 1 female : 2 males d. 1 female : 3 males e. 3 females : 1 male
Males and females are both born with all the gametes they will produce in a lifetime. True or False?
In gametogenesis in both human males and females: (Select all that apply.) diploid stem cells are the precursors to haploid gametes. secondary spermatocytes and secondary oocytes undergo both meiotic divisions in quick succession to produce mature gametes secondary spermatocytes and secondary oocytes form by meiosis from primary spermatocytes and primary oocytes. stem cells form during embryonic development and divide by mitosis. all primary spermatocytes and primary oocytes divide by meiosis.
1. The human genome contains approximately _________ base pairs. 2. What are gametes? Provide two examples of human gamete cells. 3. Describe homologous chromosomes 4. True or False: Chromosomes packed together with histones are called chromatid. 5. True or False: Karyotyping is useful in illustrating the number of chromosomes. 6. In karyotyping, the chromosomes are stained with a ____-binding dye called a _______ stain. 7. What is the function of trypsin? 8. What does GTG stand for?
1.All cells in a human body undergo the process of meiosis. True False 2. Most cells in the human body contain 46 chromosomes. True False 3. The chances that any two siblings will be genetically identical is astronomically small. True False 4. Each time protein synthesis occurs; all of the DNA of a cell is copied. True False RNA creation occurs in the nucleus of a cell; protein synthesis occurs on the ribosomes. True False 6. Tay-Sachs syndrome is a...

6 True/False: Mark the following statements as true (T) or false (F). If the statement is false, correct it to make it a true statement. a. Gametes result from two rounds of cell division. b. Meiosis results in diploid cells. C. Homologous chromosomes overlap at points called chiasmata or crossover. d. The DNA replicates prior to the start of meiosis II. 7 Number the following events of spermatogenesis in the proper order, with number 1 next to the first event...
