Leave any statements that are false (that you do not agree with) un-selected.) OA triploid cell should have three different chromosomes in its genome, meaning N = 3. O If N = 9, then a triploid cell should have a total of 27 chromosomes. O This cell should have three sets of the genome for this species. This cell should have three homologous chromosomes for each kind of chromosome. One triploid cell should produce three triploid cells after completing mitosis.

Adams maternal and paternal chromosomes have alternate forms of a gene that influences whether a person is right-handed or left-handed. One form says right and its partner says left. Visualize one of Adams spermatogonia, in which chromosomes are being duplicated prior to meiosis. Visualize what happens to the chromosomes during anaphase I and II. (It might help to use toothpicks as models of the sister chromatids of each chromosome.) What fraction of Adam's sperm will carry the gene for right-handedness? For left-handedness?
Which of the following correctly describes the gametes that will form as a result of nondisjunction during anaphase II in a human male? Select one: a. Two sperm with chromosomes and two sperm with chromosomes b. Two sperm with chromosomes, one sperm with chromosomes, and one sperm with chromosomes c. Four sperm with chromosomes d. Four sperm with chromosomes
Which of the following correctly describes the gametes that will form as a result of nondisjunction during anaphase II in a human male? a. Two sperm with 24 chromosomes and two sperm with 22 chromosomes b. Two sperm with 23 chromosomes, one sperm with 22 chromosomes, and one sperm with 24 chromosomes c. Four sperm with 24 chromosomes d. Four sperm with 22 chromosomes
Describe one function, brought about by the process of meiosis thatspermatogenesis and oogenesis have in common. Please write the similarities between spermatogenesis and oogenesis in a paragraph ratherthan a table. Please discuss the process mentioning differentiation, multiplication anddivision. How many stages of meiosis do they go through. Please mention if haploid ordiploid cells are formed.
During spermatogenesis, which of the following options describes when cytokinesis would occur? Following anaphase I Following metaphase II Following telophase I Following telophase II
In human spermatogenesis, mitosis of a stem cell gives rise to one cell that remains a stem cell and one cell that becomes a spermatogonium. Draw four rounds of mitosis for a stem cell and label; the daughter cells. For one spermatogonium, draw the cells it would produce from one round of mitosis followed by meiosis. Label the cells, and label mitosis and meiosis. What would happen if stem cells divided like spermatogonia?
A sperm cell from the fruit fly Drosophila melanogaster contains four chromosomes. How many chromosomes would be present in a spermatogonial cell about to enter meiosis? How many chromatids would be present in a spermatogo- nial cell at metaphase I of meiosis? How many would be present at metaphase II?
Humans have 46 chromosomes in each somatic cell.a. How many chromosomes does a child receive fromits father?b. How many autosomes and how many sex chromosomes are present in each somatic cell?c. How many chromosomes are present in a humanovum?d. How many sex chromosomes are present in ahuman ovum?
A human male named Phillip has an X chromosome that ismissing its Xic. Is this caused by a new mutation (one that occurredduring gametogenesis), or could this mutation have occurred in anearlier generation and be found in the somatic cells of one of hisparents? Explain your answer. How would this mutation affect hisability to produce viable offspring?
Is each of the following cell types haploid or diploid? How does eachcell type relate to the others?a. An oogoniumb. A primary spermatocytec. A spermatidd. A secondary oocytee. A polar body derived from a primary oocyte
Most sexual organisms are either male or female though some are hermaphroditic. In human beings and Drosophila (fruitfly), the sex of an individual is determined by the kind of sex chromosomes they possess. Males have two types of chromosomes, a big chromosome X and a small chromosome Y while females have only one kind, 2X or XX. The X and Y chromosomes segregate during the formation of mature spermatozoa (sprematogenesis) so that a mature sperm contains only either X or Y. What is the probability of getting an X-bearing sperm? A Y-bearing sperm? How many kinds of ova as to the kind of sex chromosome present can be produce? Determine the probability of getting a boy or girl. Show your calculations.
