Genes are not copied EXACTLY the same. There is some variation, this variation could mean you have a gene that helps or hinders you :D
Meiosis involves two rounds of cell division (meiosis I and meiosis II) to reduce the chromosome number and ensure genetic diversity. The first division separates homologous chromosomes to produce haploid cells, and the second division separates sister chromatids to produce gametes with unique genetic combinations.
Meiosis and fertilization are important because they allow for genetic diversity in offspring, which increases the chances of survival in changing environments. Meiosis ensures that offspring have a unique combination of genes, while fertilization combines genetic material from two parents to create variation. This genetic diversity helps species adapt to new challenges and increases the likelihood of successful reproduction.
Meiosis exists to ensure genetic diversity and reduce chromosome number in gametes, helping to maintain the correct chromosome number in the offspring. It also facilitates sexual reproduction by producing haploid gametes that combine to create genetically unique offspring.
The basis of alignment in meiosis I is the pairing of homologous chromosomes, where they line up side by side to form tetrads. This allows for genetic recombination to occur between the homologous chromosomes. In meiosis II, alignment is based on the alignment of sister chromatids to ensure that each daughter cell receives one copy of each chromosome.
Meiosis is important in organisms because it leads to genetic diversity by creating gametes with unique combinations of genes. This genetic diversity is essential for the survival of the species by ensuring adaptability to environmental changes and creating variability among individuals for natural selection to act upon. Additionally, meiosis helps maintain a stable chromosome number across generations.

Um, Life? Survival of the fitest? Sex? Profit?
so it doesn't die.
yes very possibly the fitest
the fitest survive

chromosomes, leading to genetic variation through recombination of genes. Meiosis halves the number of chromosomes in gametes, ensuring that the offspring will have the appropriate chromosome number when fertilization occurs to restore the full set. This genetic variation enhances adaptability and diversity within a species, increasing the chances of survival in changing environments.
The selection of the organism that survives best in a habitat with limited resources and that organisms superior reproductive success is called natural selection.
Yes that's why when you have a skunk living near you , you should get it away as soon as possible :)
