In this project, you will analyze claims about the causes of inherited genetic variation. You will then make your own claim based on prior knowledge. Next, you will defend your claim by conducting research to gather information that supports it. Finally, you will present your claim and defense in a typewritten paper.

The two major causes of the inherited genetic variation are 1-mutations during DNA replication and 2-crossing over during meiosis

Explanation:

The mutations are changes in the genetic information that may be inherited when they occur in germline cells (i.e. sperms and ova). Mutations include single nucleotide polymorphisms (SNPs), insertions and deletions (collectively named indels), and major chromosome arrangements such as, for example, aneuploidy, centric fusion, duplications, etc. On the other hand, the crossing over or recombination is the exchange of genetic material between non-sister chromatids of homologous chromosomes during Prophase I of Meiosis. Recombination is a phenomenon that generates new genetic combinations in the gametes and thus increase genetic diversity. Both germline mutations and crossing over events increase genetic variation in the offspring of the next generation, thereby these phenomena represent sources of inherited variation.

cramming before a final is bad because it makes a student's stress level higher. students who embrace cramming to get through a final exam week find themselves struggling to perform consistently, once the brain adjusts to prolonged sleep deprivation.

sheep is a herbivore animal whereas grasshopper belongs to the class chordates but both of them feed on greens.  

if grasshopper and sheep feeding on a pasture land, i do not think both of them will have any impact on each other. however, the number of the species can make difference. since sheep feed on greens, there is a possibility there left no pasture land for the grasshoppers or they may get extinct.
