Answer: Genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).
By the end of meiosis, the resulting reproductive cells, or gametes, each have 23 genetically unique chromosomes. The overall process of meiosis produces four daughter cells from one single parent cell.
Explanation:
During meiosis, homologous chromosomes (1 from each parent) pair along their lengths. The chromosomes cross over at points called chiasma. At each chiasma, the chromosomes break and rejoin, trading some of their genes. This recombination results in genetic variation.
Linnaeus. Carolus Linnnaeus is a Swedish naturalist whose lasting achievement is binomial nomenclature; it is a system of naming and classifying plants and animals according to genus and species.
Answer:
Climate models can show the composition of the atmosphere in the future.
Explanation:
Climate models help predict how the average conditions will change in a region and they also serve as an extension of weather forecasting. They are quite broad and can make analysis and predictions over long time spans.
These models are generated from some set of mathematical principles with different data points numbering over a thousand. These large data points help increase the accuracy of the models.
