Why do germ cells undergo meiosis and somatic cells don't?Question:Why do germ cells undergo meiosis and somatic cells don't?Meiosis:Meiosis is a type of cell division which produces four daughter cells, each with its own unique genetic complement. It also produces cells which have half ...
Which type of cells do meiosis form? These cells are our sex cells – sperm in males, eggs in females. During meiosis one cell? divides twice to form four daughter cells. These four daughter cells only have half the number of chromosomes? of the parent cell – they are haploid. Meiosis...
Why do animal cells undergo Meiosis? Explain why meiosis leads to significant genetic variation while mitosis does not. Why does meiosis consists of two cell divisions? (a) Why is genetic variation so important? (b) Does meiosis result in this variation? Why? Explain how the process of m...
Mitosis is the scientific and biological process that involves the separation of one single cell, thereby producing two identical sets of cells, each of which contains a nucleus. After following a certain specific cycle that cells undergo, the process of mitosis is naturally undergone to complete ...
Meiosis makes the cells needed for sexual reproduction to occur, and mitosis replicates non-sex cells needed for growth and development.Is mitosis a 2n?Both diploid and haploid cells can undergo mitosis. This makes a lot of sense, because mitosis is essentially like making a photocopy: it ...
Sexual reproduction is ubiquitous in eukaryotes, but the mechanisms by which sex is determined are diverse and undergo rapid turnovers in short evolutionary timescales. Usually, an embryo’s sex is fated at the moment of fertilisation, but in rare instances it is the maternal genotype that determin...
(Villeneuve and Hillers2001; Mercier et al.2015). While homologous recombination already existed in prokaryotes and often accompanies repair of DNA damage in somatic cells, a specific recombination pathway with unique features is responsible for the formation of most crossovers during meiosis in plants...
Why do some cells in onion root tips undergo mitosis? Mitosis and Meiosis: Mitosis and meiosis are two types of cell division that each is used for certain functions. Mitosis is the type of cell division that is used for repairing cells and replacing them when they are damaged. On the oth...
How does a Fertilised egg undergo cell division? For the first 12 hours after conception, the fertilized egg remains a single cell. After 30 hoursor so, it divides from one cell into two. Some 15 hours later, the two cells divide to become four. And at the end of 3 days, the fertil...
Where do primordial germ cells migrate from? Follicular Development in Mammals. During embryogenesis, primordial germ cells migrate fromthe yolk sac through the dorsal mesentery of the hindgut to the genital ridge. The germ cells undergo extensive proliferation, and somatic cells derived from the mese...
