Homework Answers
12. B) II
During anaphase II, the sister chromatids of each duplicated chromosome are pulled apart. They then move toward opposite ends of the cells.

1. Draw TWO PAIRS of metacentric homologous chromosomes as they would appear, if they could be seen, during of the cell cycle. Indicate centromeres with a small circle. For one pair of homologs, place the allele on one chromosome and the allele a on the other chromosome. For the other pair of homologs place the allele on one chromosome and the alleleb on the other chromosome. 2. Draw the same chromosomes as they would appear at the end of prophase...

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?...

2n=2 the homologous pair of chromosomes are Acrocentric. draw this cell during anaphase of mitosis and shade paternal chromosomes.
Homologous chromosomes pair along their length during prophase 1 of meiosis.
Question 36 Homologous chromosomes pair along their length during prophase 1 of meiosis. While two homologues are paired, genetic exchange may occur between them in a process called _______ syngamy nondisjunction independent assortment crossing over Question 37 At the end of meiosis II, there are _______ 2 haploid daughter cells that are genetically different 4 haploid daughter cells that are genetically identical 4 haploid daughter cells that are genetically different 2 diploid daughter cells that are genetically identical 4 diploid daughter cells that are genetically differentQuestion 38 When do homologous chromosomes separate from...

2a. Draw a pair of homologous chromosomes as they would be matched during prophase I if they had a paracentric inversion. (be sure to give yourself plenty of space so drawing is clear) Let the original gene order on these chromosomes be: L, M, N, centromere, O, P, Q, R, S, T. Let one of the chromosomes contain an inversion that includes P, Q, and R. Remember that the chromosomes are duplicated at this time, and thus contain sister chromatids....

Number of Chromosomes in Human Cell at Difference Stages of Melosis Identify the number of chromosomes in a typical human GERM cell during each stage of meiosis. For each stage, choose either 23 or 46 chromosomes. - Prophase - Metaphase 1 Anaphase - Telophase A 23 - Prophase II B. 46 - Metaphase II - Anaphase 11 - Telophase 11

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...

2) What is being separated during anaphase of mitosis? a. centrosomes b. cytoplasm c. nuclear membranes d. sister chromatids e. plasma membranes 3) What event occurs in both anaphase of mitosis and anaphase II of meiosis II? a. Cytokinesis ends. b. Homologous chromosomes pair. c. Homologous chromosomes separate. d. Sister chromatids separate. e. Chromatin decondenses.

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
