Two examples of related organisms are dinosaurs/chickens, and the megalodon/the great white shark.
<h3>How have organisms evolved?</h3>
Life emerged on our planet 3.7 billion years ago, and since then organisms have evolved or changed over time this includes:
- The appearance of more complex organisms, which is the result of natural selection.
- The diversification of organisms.
- The extinction or disappearance of species.
This has caused all organisms that exist today to be related to other organisms of the past. Let's examine two examples.
<h3>Dinosaurs and chickens: </h3>
According to scientific research, birds evolved from dinosaurs. Indeed, it has been determined birds started with theropods, which were a specific group of dinosaurs.
This means modern birds including chickens are related to this group of dinosaurs, even if overtime birds have evolved a lot and they might not seem to be very similar to dinosaurs.
<h3>The megalodon and the great white shark:</h3>
These two species of shark likely share a common ancestor and due to this, both species have many similarities such as the shape of their teeth. However, megalodons are extinct, while great white sharks still exist today.

Genes have two alleles.
Some genes have a variety of different forms, which are located at the same position, or genetic locus, on a chromosome. Humans are called diploid organisms because they have two alleles at each genetic locus, with one allele inherited from each parent. Each pair of alleles represents the genotype of a specific gene.

Answer:
Both mitosis and meiosis are processes of cell division. They use the same steps for cell division, including prophase, metaphase, anaphase and telophase.
Differences between mitosis and meiosis:
Mitosis is the process of asexual reproduction, while meiosis involves sexual reproduction. Higher life forms, such human beings and animals undergo meiosis. The resulting offspring is genetically different in the case of meiosis, while the offspring is identical in the case of mitosis. Meiosis includes two steps of division, compared to the single step of mitosis. During the process of meiosis, the number of chromosomes is reduced by half, while in mitosis, they remain the same. Also, mitosis produces 2 diploid cells, while meiosis produces 4 haploid cells.
