Which describes the cells at the end of meiosis?
Meiosis I separates homologous chromosomes and meiosis II separates sister chromatids. Which describes the cells at the end of meiosis I? The cells are haploid.
Which describes the cells at the end of mitosis one?
At the end of mitosis, the two daughter cells will be exact copies of the original cell. Each daughter cell will have 30 chromosomes. At the end of meiosis II, each cell (i.e., gamete) would have half the original number of chromosomes, that is, 15 chromosomes.
Are the cells the same at the end of meiosis?
Like mitosis, meiosis is a form of eukaryotic cell division. … Mitosis creates two identical daughter cells that each contain the same number of chromosomes as their parent cell. In contrast, meiosis gives rise to four unique daughter cells, each of which has half the number of chromosomes as the parent cell.
Which describes the cells at the end of meiosis when nondisjunction occurs during meiosis?
Nondisjunction Produces Abnormal Gametes
If nondisjunction occurs during anaphase I of meiosis I, this means that at least one pair of homologous chromosomes did not separate. The end result is two cells that have an extra copy of one chromosome and two cells that are missing that chromosome.
What occurs at the end of meiosis I quizlet?
At the end of meiosis I, there are two haploid cells, each with two sister chromatids per chromosome. … four haploid cells, with each chromosome consisting of a single chromatid. Replication of chromosomes occurs between meiosis I and meiosis II.
Which describes the cells at the end of meiosis II?
Meiosis II starts with two haploid parent cells and ends with four haploid daughter cells, maintaining the number of chromosomes in each cell.
Which statement correctly describes the relationship between the cells at the end of meiosis II and the original cell?
Which of the statements below correctly describes the relationship between the cells at the end of meiosis II and the original cell? The new cells have one copy of half of the genetic information in the original cell. At the end of the meiosis II are four daughter cells.
Are the cells at the end of meiosis 1 identical?
At the end of meiosis-I, two daughter cells are formed having half the number of chromosomes present in diploid cell undergoing meiosis. … Each cell has half the number of chromosomes present in the diploid cell. Each cell is identical as far as the number of chromosomes is concerned.
What do the cells look like at the end of meiosis compared to how the one cell started )?
In metaphase II, the chromosomes line up individually along the metaphase plate. In anaphase II, the sister chromatids separate and are pulled towards opposite poles of the cell. In telophase II, nuclear membranes form around each set of chromosomes, and the chromosomes decondense.
How does the end result of meiosis differ from the end of mitosis?
Mitosis produces two diploid (2n) somatic cells that are genetically identical to each other and the original parent cell, whereas meiosis produces four haploid (n) gametes that are genetically unique from each other and the original parent (germ) cell.
How do the resulting cells at the end of meiosis compare to the original cell from the beginning of meiosis?
Meiosis employs many of the same mechanisms as mitosis. However, the starting nucleus is always diploid and the nuclei that result at the end of a meiotic cell division are haploid, so the resulting cells have half the chromosomes as the original.
Which of the following statements about the products produced when nondisjunction occurs during meiosis I is true?
Which of the following statements about the products produced when nondisjunction occurs during meiosis I is true? Nondisjunction during meiosis I yields two gametes that are missing a particular chromosome after meiosis II. … The term applied to an individual with 25 chromosomes would be triploid. False.
What happens during nondisjunction in meiosis?
Nondisjunction occurs when homologous chromosomes or sister chromatids fail to separate during meiosis, resulting in an abnormal chromosome number.
What happens during nondisjunction and the effect on the resulting cells?
There are three forms of nondisjunction: failure of a pair of homologous chromosomes to separate in meiosis I, failure of sister chromatids to separate during meiosis II, and failure of sister chromatids to separate during mitosis. Nondisjunction results in daughter cells with abnormal chromosome numbers (aneuploidy).
