A monogenic gene gives rise to a trait from a single set of alleles. AP Biology Mitosis and Meiosis Quiz | Biology Quiz - Quizizz Meiosis starts from a parent cell that is diploid but will end up producing four haploid gamete cells. Mitosis is a continuous process of cell division which occurs in all types of living cells. The resulting offspring all produced terminal flowers because the allele for terminal flowers is recessive. At this point in the cell cycle the sister chromatids are held together tightly at the centromere. answer choices . In one person, one allele might code for blue eyes and the other allele codes for green eyes. A) one allele from each parent. D) sister chromatids are pulled apart during meiosis I, but not during mitosis. In eukaryotic cells, the time and phases from the beginning of one cell division until the beginning of the next cell division is called the cell cycle (Figure 1). We give Mitosis And Meiosis Quiz With Answers Pdf and numerous book collections from fictions to scientific research in any way. 18. It is very useful for everyone. Metaphase: Spindle fibers (called kinetochore microtubules or kinetochore spindle fibers) that emanate from the centromeres attach to the kinetochore (a proteinaceous area) on the sister chromatids. The first round of division is special, but the second round is more like mitosis. D) 1/8. A) Oak trees get taller as they grow. Define mitosis and meiosis, and describe the differences between these two processes. Because the number of alleles was reduced during meiosis . Figure 8. Each nucleus is identical to the original nucleus as it was in G. Meiosis is the form of nuclear cell division that results in daughter cells that have one-half the chromosome numbers as the original cell. B. B) two alleles from each parent. The mitotic cell cycle is initiated by the presence of certain growth factors or other signals that indicate that the production of new cells is needed. Does mitosis or meiosis result in four haploid gametes? Mitosisinvolvesfour basic phases prophase, metaphase, anaphase and telophase. B) the four copies of a chromosome that are normally present in cells. Mitosis: The resulting daughter cells in mitosis are genetic clones (they are genetically identical). B) incomplete dominance.

Thus, unlike the two genetically identical cells produced in mitosis, the meiotic cell cycle produces four cells that are genetically different. The primary function of mitosis is general growth and repair. It is divided into several stages that include, prophase, metaphase, anaphase and telophase. Thanks a lot, It is very informative and easily understood able also. What is the outcome when a cell undergoes meiosis? To increase in number, they must divide. asheemalik98. In preparation for meiosis, a germ cell goes through interphase, during which the entire cell (including the genetic material contained in the nucleus) undergoes replication. Both processes have a growth period called interphase, in which a cell replicates its genetic material and organelles in preparation for division. 2. B) polygenic inheritance. In prophase I of meiosis, crossing over results in [{Blank}]. Mitosis versus meiosis. While the processes of mitosis and meiosis contain a number of differences, they are also similar in many ways.

A) skin In mitosis, the genetic material (DNA) in a cell is duplicated and divided equally between two cells. Therefore, when meiosis is completed, each daughter cell contains only half the number (n) of chromosomes as the original cell. Unlike mitosis, meiosis results in the formation of a two genetically The main function of the meiotic division is the production of gametes (egg cells or sperm cells) or spores. The joining together of a sperm and egg during fertilisation returns the number of the chromosomes to 46. 1.5: Mitosis and Meiosis I - Biology LibreTexts The gametes can then meet, during reproduction, and fuse to create a new zygote. Meiosis is a process that gives rise to a haploid cell from a diploid one. -Meiosis produces 4 haploid cells. During which phase of mitosis do the chromosomes line up along the middle of the dividing cell? Are there more shakes in a second than there are seconds in a year? Telophase: The non-kinetochore microtubules continue to elongate, further elongating the cell in preparation for cytokinesis (splitting of the cytoplasm). This division occurs in the reproductive organs (gonads -- testes of males or ovaries of females) of species that reproduce sexually, and results in the formation of gametes (eggs or sperm) that contain half the number of chromosomes as the original cell. I like it. D) Diploid cells. How do mitosis and meiosis differ? Both mitosis and meiosis involve phases: Prophase, Metaphase, Anaphase and Telophase. What type of cellular reproduction is the mitosis process? The answer is A because meiosis reproduces asexually which means they are able to inherit the genes of only one parent.
