All somatic cells undergo mitosis, whereas only germ cells undergo meiosis. Meiosis is very important because it produces gametes (sperm and eggs) that are required for sexual reproduction. Human germ cells have
When does mitosis occur in humans? Does nondisjunction occur in mitosis? Is meiosis a part of the cell cycle? Where in somatic cells does mitosis occur? Is embryonic development caused by mitosis or meiosis? What happens before mitosis?
Answer to: The cause of Down syndrome is due to the presence of an extra chromosome. Do you think this mutation would occur in meiosis or mitosis?...

In order to compare questions produced by different question generation teams, Rus et al. (2010) identified five criteria for humans to use in judging the quality of questions: syntactic correctness, ambiguity, relevance, question type, and variety. Although the first two criteria,syntactic correctne...
It may be preceded by a premeiotic endomitosis (Dawley and Bogart, 1989) or include an endomeiosis without separation of the two cells and followed by a gathering of the two chromosomal sets (Simon et al., 2003). This gathering may also concern two cells resulting from distinct meioses....
After a 1–3 month period of dormancy, the zygospore undergoes meiosis to form four haploid nuclei (two of each mating type) and germinates to form a sporangium. Sporangiospores are formed by mitosis; these spores are homokaryotic; one-half of the spores are of one mating type, and ...
Meiosis Prophase I The chromosomes are completely condensed.

Compare Mitosis and Meiosis by addressing in which type of cells they occur, how many cells are produced, the ploidy of the cells produced and whether cells produced are identical to the parent cells or different. In what ways is meiosis II similar to and different from mitosis of...
