meiosis 1 is called reductional division because number of chromosome reduce and meiosis 2 is called equational division because it contain same number of chromosome as before.
please help fill in the tables. Part 2: Meiosis Meiosis S G2 Prophase I and prometaphase...
Simulate meiosis by drawing One pair of chromosomes and no crossing over Instructions: Set up your cell. The cell you start with should be: A diploid cell It should contain 1 pair of homologous chromosomes It should be in G1 of the cell cycle, before DNA replication occurs Be sure to show 2 genes that are both heterozygous . Go through the steps of meiosis. Be sure to show and label these in your pictures: Label homologous chromosomes and sister...
SUMMARY – COMPARE MITOSIS AND MEIOSIS 1. What structures are present in the phases? How many? (Use numbers like 2n, 1n, etc., and terms like dyads, tetrads, replicated chromosomes, chromatids, chromosomes, ...) Phase Mitosis Meiosis I Meiosis II Prophase Metaphase Anaphase Telophase Cytokinesis Ploidy level after all divisions of 2n cell Number & type of cells produced by division(s) Function in life cycle
HILMIUSIS AND MEIOSIS 1. What structures are present in the phases? How many? (Use numbers like 2n, 1n, etc., and terms like dyads, tetrads, replicated chromosomes, chromatids, chromosomes,...) Mitosis Phase Prophase Meiosis Meiosis II Metaphase Anaphase Telophase Cytokinesis Ploidy level after all divisions of 2n cell Number & type of cells produced by division(s) Function in life cycle
Can someone please check my answer? Understanding chromosome number and behavior during cell division is an important concept in genetics. Fill out the chart below for each phase of mitosis in terms of N (where N = haploid number). For example, humans have a haploid number of 23. There are 46 chromosomes (2N) present in prophase of mitosis. Each chromosome is present in its replicated form (i.e. as sister chromatids) so there will be 2 chromatids per chromosome and the...
Simulate meiosis by drawing Two pairs of chromosomes with crossing over Assume that two of the genes are on chromosome 1, and one of the genes is on chromosome 2. Allow crossing over to occur between the two genes on the same chromosome. Also, are there multiple ways that the chromosomes could segregate to produce different results? Show them. Instructions: Set up your cell. The cell you start with should be: A diploid cell It should contain 2 pairs of...
For each phase (G1, G2, Prophase, Metaphase, Anaphase, & Telophase/Cytokineses) What are/ What is the: 1N 2N Linear DNA Chromosomes Replicated chromosomes Chromatids Centromeres Kinetochores Autosomes (chromosomes) Sex Chromosomes Paternal autosomes Paternal autosomal chromatids Maternal autosomes Maternal autosomal chromatids Tetrads Is this a 1N or 2N cell? What process is this?
If you have 200 ng of DNA in the G2 phase of the cell cycle, how much DNA will you have in prophase of mitosis? in prophase I if meiosis? in prophase II of meiosis? in telophase II of meiosis? How many strands (molecules) of DNA are there per chromosome in prophase of mitosis? in prophase I if meiosis? in prophase II of meiosis? in telophase II of meiosis?

Please help me with this. I'm so lost. If you could be detailed/help explain, I would appreciate it a lot. Thank you. Topic: Onions, Lily Anther, Mitosis and Meiosis!: Prophase I, Prometaphase I, Metaphase I, Anaphase I, Telophase I, Cytokinesis Prophase II, Metaphase II, Anaphase II, Telophase II, Cytokinesis II Tetrads Intro Pretend you were in the lab and you took some onion root tips and some lily and viewed them under the lab in a microscope. We are Concerned...
• In the cell, DNA is duplicated in the G1 phase S phase G2 phase Division stage Which of the following statements is true? Chromatin is more compacted in prophase than during the G2 phase The key even of Sphase is the segregation of sister chromatids • • The mitotic spindle first appears during anaphase The cell increases in size during metaphase Which of the following correctly represents the order of the phases in the cell cycle? Mitosis, S phase,...
