Mitosis and meiosis, respectively分别, make simple cell division and sexual reproduction possible. Each means of passing on hereditary 遗传 information has advantages. In asexual 无性的 reproduction the parent organism生物体 gives rise to offspring 后代that are genetic clones of the parent. The advant...
Sexual reproductionAsexual reproduction Basic biological processes: gametogenesis (mitosis and meiosis), copulation, and fertilizationBasic biological process: mitosis Involves sex cellsDoes not involve sex cells Offspring is genetically distinct from the parentsOffspring is a clone of the parent ...
Since asexual reproduction usually happens in simpler organisms, any cell is capable of reproduction. Therefore, asexual cells are any somatic cell for a single-celled organism. Mitosis is the splitting of a somatic, or body cell, into two identical cells. These can either be new organisms or ...
Asexual Reproduction Type of reproduction by which offspring arise from a single organism. Produced by mitosis. Offspring inherit the genes of only. Asexual & Sexual Reproduction Asexual Reproduction Type of reproduction in which a new organism is produced from ONE parent and the offspring is identica...
1. the process of reproduction. 2. a class composed of all individuals removed by the same number of successive ancestors from a common predecessor, or occupying positions on the same level in a genealogical (pedigree) chart. alternate generation reproduction by alternate asexual and sexual means ...
cell cyclethe cycle of biochemical and morphological events occurring in a reproducing cell population; it consists of theS phase,occurring toward the end of interphase, in which DNA is synthesized; theG2phase,a relatively quiescent period; theMphase, consisting of the four phases of mitosis; and...
Asexual reproduction is reproduction without sex. In this form of reproduction, a single organism or cell makes a copy of itself. The genes of the original and its copy will be the same, except for rare mutations. They are clones. The main process of asexual reproduction is mitosis. This ...
• In asexual reproduction, there is either no reduction division (apomixis) or the product cells of one individual's reduction division fuse together again (automixis); It is easy for a mutation to convert meiosis into mitosis, and thus a sexually reproducing into an asexually reproducing fem...
3. The spores in asexual reproduction are asexual spores, which share the same chromosome number or DNA number as somatic cells. Therefore, asexual spores are produced only by mitosis or mitosis, but not by meiosis. 4, the nutrition reproduction is to reproduce the nutritional organs of plant,...
Types of Asexual Reproduction Regeneration 1. Repair/ grow lost body parts 2. Left over cells divide to make more cells 3. Lobsters, starfish, lizards The numbers The cells created from mitosis are diploid or 2n. The cells created from meiosis are haploid or n Definitions: Diploid (2n) –...
