A) How do the new cells compare to the original cell with regard to genetic information present and number of chromosomes present?
B) Does each cell still have two matching large and two matching small chromosomes?
C) For each maternal chromosomes is there a homologous paternal chromosome?
D) If the answer to the previous two questions is yes, then the new cells are ______ (diploid or haploid) and the 2n number of chromosomes is______.
For B and C, I having a hard time understanding the chromosomes and 2n versus 4n. Please help, thanks!
involving Telophase, what information do u need

2. A diploid cell contains two pairs of chromosomes, which we will call 1 and 2. Assume chromosome! is clearly larger than chromosome 2. Each chromosome pair contains a maternal and a paternal member (e.g. 1 and 1 & 2 and 2"). An allele called G is localized to 1" whereas an allele called g is on chromosome 1P. Allele R is localized to 2m whereas alleler is localized to 2. Using these designations and clearly drawn and labeled chromosomes,...
alagy and Early Develapment Leberatory 2. Identify Homologous Chromosomes and Sister Chromatids in appropriate phases. What are homologous chromosomes? Are they present in all cells? If not, which cells lack homologous chromosomes? Are they present in all stages of mitosis? Are they present in all stages of Meiosis 1? Meiosis II? How do the terms haploid and diploid relate to the presence/absence of homologous chromosomes? What are sister chromatids? During what phase of the cell cycle do sister chromatids form?...
underers meiosis, how many cells will result, 12) If a eukaryotic cell has 20 chromosomes and and how many chromosomes will they contain? A) 4 cells, each with 20 chromosomes B) 4 cells, each with 10 chromosomes C) 2 cells, each with 10 chromosomes D) 2 cells, each with 20 chromosomes Answer: 13) Crossing over occurs during which stage of meiosis? A) telophase I B) metaphase II C) anaphase II D) prophase II E) prophase I Answer: 14) Which of...
Fill in the blank: 11. A cell with a diploid number of 20, undergoes meiosis. This will produce daughter cells, each with __ _ chromosomes. 12. Crossing over occurs during this phase: 13. Tetrads line up along the equator during this phase: 14. At the end of meiosis I, daughter cells are created. These daughter cells are ( diploid | haploid ). 15. Meiosis creates what type of cell: Fill in the Blank with the proper phase of Meiosis (Interphase...
20. How many cells are formed at the end of Meiosis I & how many copies of chromosomes does each cell have?_ 21. Is DNA copied before Meiosis II? _ 22. How many cells form at the end of Meiosis II and how many chromosomes do they contain? • 23. Oogenesis ultimately gives rise to (one ovum, four ova) with the Chaploid, diploid) number of chromosomes. 24. A sperm cell is a (gamete, zygote), and is (haploid, diploid). 25. When...
Compare mitosis and meiosis by filling in the chart below. Meiosis Mitosis Characteristic Are daughter cells genetically identical or different from the parent? Involves how many cell divisions? Produces how many daughter cells? Produces haploid or diploid cells? Produces what type of cell? Sister chromatids or homologous chromosomes separate? What are the functions of the cells produced? 05 Answer the following Explain how segregation of chromosomes during meiosis can generate four types of gametes (assume four chromosomes, two homologous pairs)...
1. Represent all chromosomes in a 2n = 4 cell before replication. Number the homologous chromosomes as you would in a karyotype (e.g., Chromosome 1, Chromosome 2). 2. Gene F is on Chromosome 1 and gene G is on Chromosome 2. This cell carries two different alleles of gene F (called F and f), and two different alleles of gene G (called G and g). Label these alleles on the unreplicated chromosomes that you drew above. 3. In the space...
3. A diploid cell with eight chromosomes undergoes meiosis. (7 pt) a. How many chromosomes are there in each cell after meiosis I? How many daughter cells are made after meiosis I? Are the daughter cells diploid or haploid? (1.5 pt) How many chromosomes are there in each cell after meiosis ll? How many daughter cells are made after meiosis II? Are the daughter cells diploid or haploid? (1.5 pt) What two mechanisms allow genetic variation among the gametes produced...
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...
Can anyone help me with this? Thank you.
Lab 13. Mitosis and Meiosis Purpose The purpose of this lab is to understand the process of mitosis and melosis in animal and plant cells. Learning Objectives After completing this lab, you will be able to: 1. Describe the stages of mitosis. 2. Identify the stages of mitosis in an onion root or whitefish blastula using a light microscope. 3. Describe how cytokinesis differs in plant vs. animal cells. 4. Name and...
