Give an example of what would happen if the diploid number was not reduced to haploid before fertilization.

Haploid cells are cells that composed of only one complete set of chromosomes. The very common type of haploid cells is gametes, or sex cells. Haploid cells are produced by meiosis. They are genetically diverse cells that are used in sexual reproduction. In humans, the haploid cells have 23 chromosomes, versus the 46 in the diploid cells.  When the parent donor gives fertilized haploid cells, the offspring has a complete set of chromosomes and becomes a diploid cell. A haploid cell with have a haploid number, which is the number of chromosomes found within the nucleus that create one set. 

evidence and logical support is essential for a scientist to do in order to maintain credibility. this is because no one can believe without any logic and without any evidence.hence a scientist can maintain credibility by proving himself and by answering logically so experiments prove very beneficial. logical hypothesis give conclusion which is acceptable. therefore, there are two main factors to maintain credibility by a scientist is evidence and logical support.
