Meiosis is composed of two chromosomal division called Meiosis I and Meiosis II. Each of the two divisions consists of Prophase, Prometaphase, Metaphase, Anaphase and Telophase and each of these phases is designated I or II according to which division it is a part of. Be sure you know what happens in each phase in regard to the chromosomes, chromatids, spindles and the nuclear envelope. During which phase does synapsis occur and crossing over begin? And in which division, Meiosis I or Meiosis II...

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...

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...

The figure below shows chromosomes in a cell produced by some organism. Letters represent different kinds of genes; upper/lowercase letters represent different alleles for the same gene: e.g., purple allele (P) vs. white allele (p) for a flower color gene. 1. How many chromosomes do you see? 2. As drawn, is this cell haploid or diploid? 3. On what did you...

2. Which of the following occurs during mitosis but not during meiosis I? a. The chromosomes are pulled to opposite poles of the spindle apparatus. b. The chromatids of each chromosome are separated. c. The nuclear envelope breaks down. d. Both synapsis and crossing over take place. e. The diploid number of chromosomes is reduced to the haploid number.3. Table 1 shows the stage and number of cells and chromosomes per cell at the end of the stage in a 2n - 24 organism. u...

Draw the process of meiosis I, including each step. In this drawing denote what happens with the chromosomes and what structures form and what chromosomes are separated. Denote the two specific phases of meiosis where crossing-over and assortment occurs. Describe in detail what occurs in both of these events, including the structures created, and how they provide genetic variation in sexual reprodiction. Also denote where Mendel's law of segregation and law of independent assortment occur.

1. Draw out ALL of the stages of Mitosis AND Meiosis (I and II). Use at least 3 homologous pairs. 2. Label each stage and the hallmark of that stage. Show how chromosomes align and segregate 3. Show the points (indicate in drawing where possible) where genetic diversity is introduced AND how it contributes to diversity (Assortment of chromosomes, Random fertilization, Crossing-over between non-sister chromatids) How does trisomy 21 occur? During which stages? Indicate on your drawing for #1

1 Draw out the phases of meiosis for a (2n=4) germ line cell: Use red and blue to indicate ate the two sets of chromosomes aleat There should be two throughout the various phases-red will represent the maternal set and blue will represent the paterials alternate scenarios for how the homologous pairs could alian during metaphase. When applicable, bus pairs could alian during metaphase. When applicable, all of the phase drawings (pre-...
