How do mitosis and meiosis differ? Q 15 of 15 Meiosis occurs as sex cells reproduce and engage in crossing over, while mitosis occurs as DNA replicates itself. Mitosis occurs in females, and meiosis occurs in males in sexual reproduction. Mitosis is used to create the DNA in sex cells, and meiosis replicates cells within the body. Meiosis is involved in sex cell reproduction, which duplicates the 46 chromosomes, and mitosis is not.

..explain why meiosis occurs only in specialized cells (gametes), and that the overall goal of meiosis is to make haploid cells for sexual reproduction • ..outline the sequence of key chromosomal movements and rearrangements during the two meiotic divisions, identifying key similarities and differences between meiosis and mitosis • ..describe the ploidy of a cell before and after meiosis I and meiosis II, and how ploidy changes after separation of sister chromatids and homologous chromosomes

Which of the following correctly describes a homologous pair of chromosomes in prophase of meiosis I? a- Two replicated chromosomes, each of which is one double-stranded DNA molecule b- Four replicated chromosomes, each of which is one double-stranded DNA molecule c- Two replicated chromosomes, each of which is two double-stranded DNA molecules d- Four replicated chromosomes, each of which is two double-stranded DNA molecules

Which of the following is a result of meiosis? all chromosome line up singly at the equator the cell goes through one nuclear division two identical daughter cells are formed the daughter cells are haploid and not identical

Select two that apply. Which of the following generate genetic diversity in meiosis? homologous chromosomes are separated during anaphase II homologous chromosomes align individually during metaphase II O bivalents align independently from other bivalents during metaphase I sister chromatids exchange genetic material during prophase I homologous chromosomes exchange genetic material during prophase I meiosis goes through two rounds of division

What chromosomes belong to a normal human female?     44 autosomes and 2 X chromosomes     22 autosomes and 2 X chromosomes     44 autosomes, one X chromosome, and one Y chromosome     46 autosomes and two X chromosomes

1. What is meiosis?2. What specific cells in the body divide through this process?3. Meiosis involves two successive cell divisions. Which of the two is mitotic in nature? Why?4. What particular event in meiosis results to genetic variation? Why?5. Is there a possibility that a problem may occur at any stage of meiosis? If so, what is it and how does itaffect the organism?6. The cells produced after meiosis are haploid, how do these cells restore or maintain the normalchromosome number of the species?7. Why do you think mitosis and meiosis important in the life cycle of an organism?

Which of the following processes leads to aneuploidy, the condition of having too many or too few copies of a particular chromosome? Select all that apply.     Nondisjunction of chromosomes during mitosis   Nondisjunction of chromosomes during meiosis   Proper separation of chromosomes during mitosis   Proper separation of chromosomes during meiosis

Assume that cell does mitosis  Assume that cell does meiosis  What is the diploid number of chromosomes in this organism?  Give the number of chromosomes and the number of DNA molecules per cell present at the stages represented.  I tried to solve them, but I'm not sure what I did right and what was wrong. Please correct it for me.  See that attached photo.
