Natural polyploidy has been known for a very long time in plants, but long considered virtually impossible in nature in animals because of the so-called “Müller's rule” (Müller, 1925), until a few researchers started surveying natural populations for ploidy. Numerous cases of allopolyploid ...

We used eight seed questions to test the algorithm, one for each of these eight pairs: anabolism and catabolism, genotype and phenotype, gill and lung, mitosis and meiosis, nematode and annelid, plasma membrane and cell wall, spore and gamete, and transcription and translation The algorithm gen...
The nucleus contains DNA separated into a number of chromosomes, with the total number varying between species (humans have 46). During the process of mitosis, the nuclear membrane dissolved, chromosomes that have already been duplicated in pairs are pulled apart, and the nucleus and cell divide...
Polyploidization, the balanced amplification of the whole genome, is commonly observed in plants, insects, and fungi, as well as in some vertebrates, including frogs and fish (Gjelsvik et al., 2019, Otto, 2007). In contrast, mammalian cells are mainly diploid, and polyploidy is noted as a...
Why is it important to know about the growing habits of plants? What is the function of smooth and rough endoplasmic reticulum in plant cells? Where do plants get most of their matter? What is the difference between meiosis and mitosis? How are ribosomes measured? Of the three components of...
Why must a cell go through the S phase before mitosis? How do gymnosperms differ from ferns? Do identical twins look exactly the same when they are first born, even if they don't look alike later in life? Is it possible for two organisms to have different phenotypes but the same gen...
