The other difference between mitosis and meiosis is whether the end product is diploid or haploid. Learn vocabulary, terms, and more with flashcards, games, and other study tools. The cell has a couple of copies of each chromosome, one from the father and one from the mother. Mitosis is called the equational division while meisois is called the reductional division. What are 4 major differences between mitosis and meiosis. Genetics mitosis and meiosis rapid learning center.

Mitosis and meiosis are the two ways by which cells reproduce. Both mitosis and meiosis are types of cell division in which one cell gives rise to more than one cell. Start studying the differences between mitosis and meiosis. Mitosis and meiosis are very significant because they are the processes by which cells reproduce themselves.
This book is designed to cover all of the information that a high school biology student would need to know, and would be a good introduction or. In this article we will discuss about the similarities and dissimilarities between mitosis and meiosis. Mitosis with a t for two gives rise to two identical cells. As a result, they share several steps in their respective processes. The key difference between mitosis and meiosis is that mitosis produces two daughter cells that are genetically identical to parent cell while meiosis produces four daughter cells that contain half of the genetic material of the parent cell. Cell division is the process by which biological cells multiply. Difference between meiosis 2 and mitosis difference between.
Difference between mitosis and meiosis difference between. Describe 3 differences between mitosis and meiosis mitosis consists of one stage whereas meiosis consists of two stages. Cells divide and reproduce in two ways, mitosis and meiosis. Below we highlight the keys differences and similarities between the two types of cell division. How does the attachment of spindle fibers differ between mitosis and meiosis i. What are the differences between mitosis and meiosis.
Meiosis myohsihs is a form of nuclear division that divides a diploid cell into haploid cells. What is the difference between mitosis and meiosis 1. In this process, the produced cells are called spores or gametes. One skin cell, for instance, will divide to form two identical skin cells.
There are, however, several differences between their phases. The process of formation of new cells, from the existing ones, can occur through mitosis and meiosis, depending on the cell type and the purpose of division. This specific type of dividing cells is required for the sexual reproduction of eukaryotes. Difference between mitosis and meiosis compare the. Meiosis is different than mitosis in terms of the cell division number. Given below is a short description of the two processes followed by a detailed account of the differences between them.
Mitosis is the reason why human bodies can grow and repair themselves while meiosis is the process by which sexual reproduction occurs. The main difference between the two cycles is that the mitotic cycle lasts for more than two hours while the meiotic cycle may take days up to weeks to produce sex cells in animals because it involves meiosis 1 and then meiosis 2. Each strand of dna, or chromosome, is replicated and remains joined, resulting in two sister chromatids for each chromosome. Is anaphase i or anaphase ii in meiosis more analogous to. Mitosis results in two identical daughter cells, whereas meiosis results in four sex cells.
