The speciation, or a divergence of the population into a separate species, can take two forms:
1. Allopatric- where a physical barrier separates populations (darwin’s finches).
2. Sympatric- where the population sharing the geographic location is forced by an environmental factors to diverge.
Once they have diverged, either prezygotic or postzygotic barriers can prevent interbreeding between the two species.
Hope this helps!
True. After the first meiotic division, the cells are diploid, because the chromosomes are duplicated.
<h3>What is meiotic division?</h3>
- Meiosis is a type of cell division that results in the production of four gamete cells and a 50% reduction in the number of chromosomes in the parent cell.
- This mechanism is essential for the development of egg and sperm cells for sexual reproduction.
- The two separate cell division processes are meiosis and mitosis.
- The process of making new cells for the body, known as mitosis, is usually meant when the term "cell division" is used.
- Meiosis, a cell division process, is what creates egg and sperm cells.
- Mitosis is an essential biological mechanism.
- Two cellular divisions make up the meiotic process: To reduce the number of chromosomes in half, pairs of homologous chromosomes are divided during the first meiotic division.
- During the second meiotic division, sister chromatids are split apart.
