Meiosis
Meiosis is a procedure where one cell splits into two and gives rise to four cells accommodating half the initial quantity of genetic data. Mitosis is the splitting of a cell and results into two daughter cells with each containing a similar number and type of chromosomes as that of the initial nucleus. There are differences between these two, but the main one is, Meiosis produces two cores, while mitosis brings about four.
The modification of Meiosis occurred when eukaryotes transformed as a result of endosymbiosis between host cells that need oxygen to survive. The aim as to why Meiosis evolved is to be a successor of proteobacterium that is a predecessor of mitochondria. Meiosis is related to the film’s Why sex because all organisms that come about this process contain similar amounts of chromosomes. Meiosis evolution is substantial because it brings about genetic variation. Genetic variation is very significant because it produces living organisms with varying weaknesses and strengths. It is through this that the living things to survive in different environments because they can quickly adapt and grow its population.
Microevolution is the variation in frequencies that occurs within a given period in a population. The modifications are as a result of mutation and genetic drift. Macroevolution is a transformation on a scaled overhead or at the aligned species. Macroevolution concept of species is that it can elaborate on the life history by use of great scale patterns. A good example is, for a procedure such as mutation, it will appear microscopic scale to discover the design of the contrasts between dogs.
Speciation may occur when there is a pilling of mutations for a long time in an inhabitant or when natural selection produces living things that can breed. The genetic characteristics are a result of adaption. Some of the ancestral traits are, in human beings, they started with four legs but later transformed to having only two legs, eating using legs to use of hands and bent body structure to upright.
Geography affects malaria in various ways. Sickness is dominant in tropical regions worldwide. Areas with local weather are prone to the transmission of malaria annually, and also those with an unstable economy lack appropriate malaria control measures. The heterozygote advantage is that one sample of a disease allele is always resistant to illnesses hence protecting from other sicknesses. An excellent example is the sickle cell characteristic, which offers resistance to malaria in people with the heterozygous condition.
Sickle cell anemia is high and low according to the conditions of the geographical area. However, individuals with two copies of the alleles are prone to malaria because, at times, the cells may be misshapen while those with one are resistant.
Deforestation increases the rate of malaria spread because it creates a mosquito habitat that also increases the rate at which mosquitoes are biting human beings. Just as deforestation increases the rate of malaria, so does climate change. Climate change is a result of an increase in rainfall and temperature in high altitudes regions, and that in turn increases the mosquito habitats. As a result of this, the rate of transmission increases.
