... Chromosome number remains the same in the daughter cells. How does meiosis occur in humans? In humans, meiosis is the process by which sperm cells and egg cells are produced. In the male, meiosis takes place after puberty. Diploid cells within the testes undergo meiosis to produce ...
What are the roles of meiosis and mitosis in growth and reproduction? How does the process of meiosis produce new combinations of genes? Why is this important? Why do the daughter cells produced from meiosis 1 need to divide again in meiosis 2 Why is it important that cells produced after ...
The nebenkern is amitochondrial formationin the sperm of some insects such as Drosophila. After the completion of meiosis, spermatid mitochondria wrap around each other to form a spherical aggregate, adjacent to the nucleus. The nebenkern proceeds to elongate into a double-stranded helical structure...
How does mitosis work? What is the function of mitosis in the cell? What is the purpose of meiosis? A. To allow for growth B. To enable an organism to produce gametes C. To allow an organism to replace damaged ...
In contrast, meiosis is considered a “reductional” form of cell division that occurs in diploid germ cells. During meiosis, a diploid germ cell undergoes two cell divisions to produce four haploid gamete cells (e.g., egg or sperm cells), which are genetically distinct from the original ...
For the formation of spores, the mother cell goes through meiosis to produce haploids whereas gametes undergo fusion for the formation of diploid(2n), the zygote. The meiospore grows to develop into the gametophyte. The zygote grows to produce sporophytes ...
Found In Seed plants Animals, including humans 7 Function Develops into a seed after fertilization Develops into a new organism upon fertilization 8 Location Ovary of a plant Ovaries of female animals 8 Development Process Involves meiosis and mitosis, forms female gametophyte Formed through oogenesis,...
, male and female gametes are formed to produce an offspring. these gametes are either formed by the same individual or by different individuals of the opposite sex. this process is usually slow and complex compared to asexual reproduction. the organisms so produced are genetically diverse. thus,...
In mitosis, nondisjunction occurs when sister chromatids both go to one side rather than dividing.Wpeissner / Creative Commons Attribution-Share Alike 3.0 Meiosis As with mitosis, DNA replicates prior to gamete formation in meiosis. However, thecell divides twiceto producehaploiddaughter cells. When...
introduced into the body to produce antibodies. These antibodies protect the body from disease causing microbes. Diseases like polio, cholera, typhoid, small pox, hepatitis etc. can be prevented by taking vaccines. Microbes are also essential tools in biotechnology, biochemistry, genetics, and ...
