Charles Darwin also was the first biologist to propose the use of the phylogenetic tree or the evolutionary tree. The phylogenetic tree illustrates how organisms are related, usually by traits. It also represents how organisms are related by common ancestors. Other scientists refer to the phylogenetic tree or parts of the tree as a cladogram.
Attached is an example of a simplified phylogenetic tree.
Answer:
In the first step of meiosis I, the chromosomes/genetic material of the cell condenses into a visible form, into a form called heterochromatin. The nucleolus also disappears.
In the second step, a process called synapsis occurs. This is when homologous chromosomes align themselves, gene by gene.
In the third step, crossing over occurs. Segments of corresponding DNA are cut and exchanged between non-sister chromatids of the formed tetrads.
In the fourth step, the nucleus fragments, the nuclear envelope fragments, the two centrosomes (if we're talking about an animal cell) separate from each other as their asters and mitotic spindles (mostly microtubules (kinetochore and non-kinetochore) lengthen. The microtubules extending from the centrosomes can now connect to chromosomes.

Somatic= body cells
gametes= sperm and egg which effects future generations
