WebAlthough HGT is more common among evolutionarily related organisms, it may occur between any two species that live together in a natural community. HGT in prokaryotes is known to occur by the three primary mechanisms that are illustrated in Figure 11.26: Transformation: naked DNA is taken up from the environment. WebGenetic Variation in Meiosis. The gametes produced in meiosis aren’t genetically identical to the starting cell, and they also aren’t identical to one another. As an example, consider the meiosis II diagram above, which shows the end products of meiosis for a simple cell with a diploid number of 2n = 4 chromosomes. The four gametes produced ...

WebJan 19, 2016 · Explanation: A complete description about meiosis can be found here. In short, meiosis is a reductional division cabaple of reducing the DNA content to half by separating half the number of chromosomes in one cell called a gamete. Two factors … Prophase 1 of meiosis is where the crossing-over occur. Each of the … WebThe law of segregation states that the two alleles of a single trait will separate randomly, meaning that there is a 50% either allele will end up in either gamete. This has to do with 1 gene. The law of independent assortment states that the allele of one gene separates independently of an allele of another gene.
