Mitosis occurs in somatic cells and is responsible for the growth, development or repair of tissues and wounds in an organism. Wiki User. Answer: Option B Solution: Unlike Mitosis, Meiosis results in the formation of 4 Genetically different cells. Both the processes occur in the M-phase of the cell cycle. four diploid gametes. Meiosis is a type of cell division in sexually reproducing organisms that reduces the number of chromosomes in gametes (the sex cells, or egg and sperm). Meiosis - Genome.gov Unlike mitosis, the resulting germ cells differ in males and females. Meiosis results in daughter cells with half the number of chromosomes of the parent cell. C. careful observations. Gametes are produced in male and female gonadsandcontain one-half the number of chromosomes as the original cell. Answer to: Unlike mitosis, meiosis results in the formation of By signing up, you'll get thousands of step-by-step solutions to your homework. D) sister chromatids are pulled apart during meiosis I, but not during mitosis. Web mitosis . Explain why the DNA must be duplicated during the S phase of the cell cycle, prior to mitosis taking place. Which of the following supports the claim that the environment can affect genetic traits? Meiosis, on the other hand, is the division of a germ cell involving two fissions . From an academic perspective, understanding the difference between mitosis and meiosis is crucial. answer choices. If False, change it. PDF Biology Test: Ch. 9 Mr. Rellinger, 2014 Multiple Choice Identify the The pipe cleaner and plastic cord strands are intended to represent two pairs of homologous chromosomes. C) sex They Are Two Very Different Processes That Have Two Different Functions. Meiosis results in the formation of 4 Haploid daughter cells from one Diploid parent cell. Identify each stage shown to you by the program. What is a major difference between meiosis II and mitosis in a diploid animal? Chromosomes condense and thicken. How Long Does a Cell Spend in Each Phase of the Cell Cycle? If the Diploid number of chromosomes in carrots is 18, the haploid number is. Both processes have a growth period called interphase, in which a cell replicates its genetic material and organelles in preparation for division. A. cyclins. Don't hesitate to ask questions and start discussions whenever you need professional advice.
