for the same reason books are different even though they are written in a universal code the code is arranged differently in different books.
They can share some DNA, since your mother/father was involved in them.
different
No. Each gamete is genetically different from the other gametes and from the parent cell.
meiosis copies nd the other one does not
Basically this event is called [genetic] Recombination. Other examples exist.
Genetically inheriting diseases can be found. Other diseases are not genetic

Each parent contributes only half of their genetic material to the offspring and the merging of genetic material from each parent may result in a traits different from what the generic material invoked in each parent.
No. Each gamete is genetically different from the other gametes and from the parent cell.
Genetically modified organisms are modified on a genetic level to benefit humans. How this can pose a threat to a population or ecosystem, is that if the genetically modified organism were to somehow create a mutation, and pass that on, it could be damaging to the future generations in reducing their health or other issues may arise. It can also be damaging to an ecosystem if a genetically modified organism were to escape into a wild population and change it.

Dolphins are mammals. Sharks are fish. They are very different, though both are vertebrates.
Genetic linkage is the tendency of genes that are located proximal to each other on a chromosome to be inherited together during meiosis. Genes whose loci are nearer to each other are less likely to be separated onto different chromatids during chromosomal crossover, and are therefore said to be genetically linked.
Basically this event is called [genetic] Recombination. Other examples exist.
Individuals are genetically unique, meaning they contain genetic variation generated during recombination and chromosome assortment (and mutation) during the process of meiosis. So, each individual has a slightly different complement of genetic information. This may lead to different patterns of functionality (e.g., gene expression) under different circumstances ultimately leading to differences in appearance or responses to environmental conditions.
Yes, everybody is genetically different. Also humans (and other mammals) have sex chromosomes, two of which are normally present in female cells (designated XX) and only one in male cells (designated XY).
