Human cells normally have 46 chromosomes. For eachof the following stages, state the number of nuclear DNAmolecules present in a human cell:a. Metaphase of mitosisb. Metaphase I of meiosisc. Telophase of mitosisd. Telophase I of meiosise. Telophase II of meiosis
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?
Meiosis is defined as a ____. Select an answer and submit. For keyboard navigation, use the up/down arrow keys to select an answer. a) type of cell division that is seen in all types of cells b) type of cell division that divides a somatic cell and produces 4 gamete cells c) type of cell division that divides a somatic cell and produces 2 gamete cells d) type of cell division that divides a gamete cell into 2 somatic cells
All of the following are distinctions between the process of mitosis and meiosis EXCEPT: Group of answer choices homologous chromosomes in meiotic cells conduct synapsis meiotic cells produce genetically distinctive cells meiotic cells go through two cell divisions meiotic cells have homologous chromosomes where mitotic cells do not 2. A scientist working in an IVF (in vitro fertilization) clinic mistakenly produced a human zygote with 45 chromosomes. What biological process could explain how this happened? Group of answer choices failure of an egg to complete meiosis II failure of the egg nucleus to be fertilized by the sperm a non-disjunction in meiotic anaphase occurring in either an egg or sperm incomplete cytokinesis during spermatogenesis after meiosis I
Which one of the following entries most accurately describes the stage at which oogenesis is reinitiated? Oogenesis is reinitiated at prophase of mitosis Oogenesis is reinitiated at prophase I of meiosis Oogenesis is reinitiated at prophase II of meiosis Oogenesis is not reinitiated.
Construct a table for the different stages of meiosis, giving the number of chromosomes per cell and the number of DNA molecules per cell for a cell that begins with 4 chromosomes (two homologous pairs) in G1. Include the following stages in your table: G1, S, G2, prophase I, metaphase I, anaphase I, telophase I (after cytokinesis), prophase II, metaphase II, anaphase II, and telophase II (after cytokinesis).
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.
In regards to MEIOSIS, give the order of the following events in terms of chromosome number. Question 48 options: meiosis 1 and cytokinesis one cell containing 92 chromosomes meiosis 2 and cytokinesis a total of four cells, each containing 23 chromosomes one cell containing 46 chromosomes two cells containing 46 chromosomes
Though the stages of meiosis have the same names as the stages of mitosis, they exhibit fundamental differences. What are the main differences between the two processes? Meiosis differs from mitosis in that the number of chromosomes is halved and genetic variation is introduced in meiosis, but not in mitosis Meiosis differs from mitosis in that the number of chromosomes is halved and genetic variation is reduced in meiosis, but not in mitosis. Metaphase and telophase portions of meiosis and mitosis are the same. Meiosis and mitosis are also the same, except for the number of chromosomes. Anaphase I and anaphase are different. Prophase and telophase portions of meiosis and mitosis are the same. Meiosis II and mitosis are also the same and have the same number of chromosomes. Anaphase I and anaphase are different.
