Compare and contrast properties of sister chromatids and homologous chromosomes. Drag the appropriate items to their respective bin.
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?...
Question 5 9 pts How is meiosis anaphase I distinctly different from mitosis anaphase? Select all that apply. Hint • Meiosis Phases Part 2 u video • Textbook chapter 11 section 11.1 During melosis anaphase I the non-kinetochore spindles will separate the chromosomes, while during mitosis anaphase the kinetochore spindles will separate the chromosomes, During melosis anaphase I crossing over will take place, while mitosis anaphase does not contain any crossing over. During meiosis anaphase I the homologous chromosomes will...
Crossing over is one of the most important events in meiosis because __. A) homologous chromosomes are separated into different daughter cells B) the number of chromosomes allotted to each daughter cell must be halved C)sister chromatids must be separated into different daughter cells D) it produces new arrays of alleles on chromosomes and contributes to genetic diversity
17) Independent assortment of unlinked loci happens because (choose the best answer) A. Homologous chromosomes separate during anaphase of Meiosis 1 B. Sister chromatids separate during anaphase of Meiosis 1 C. Because of mitosis D. Because of the way zygotes behave
Meiosis generates genetic diversity by: O random segregation of homologous chromosomes in meiosis II Oneither O crossing over between non-sister chromatids in meiosis 1 both
The second division of Meiosis resembles the division in Mitosis because....... Select one: a. homologous chromosomes line up double file, in pairs, at metaphase and separate at anaphase. b. it creates two diploid cells. c. replicated chromosomes line up randomly single file in metaphase, and sister chromatids separate at anaphase. d. it occurs in diploid cells.
Match each description with the appropriate type of cell division. Match each description with the appropriate type of cell division. The new cells produced are genetically identical to each other and to the original coll During the first nuclear division, sister kinelochores fuse and are attached to the same pole Chromosomes The chromosome Independent condense before they number is reduced from Crossing over occurs assortment of maternal attach to the spindle 2 sets to 1 set and paternal chromosomes Nuclear...
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
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...
