What are some disadvantages of binary fission?
The main disadvantage of binary fission is the passing of defects and disease directly to the offspring. Another disadvantage of binary fission is the chance of evolution being low, as no recombination of genes occurs in this process.
Describe the process of binary fission in bacteria and explain how eukaryotic mitosis may have evolved from binary fission?
The evolution of Eukaryotic mitosis from binary fission is widely accepted as it parallels bacterial division among cells. Noting this commonality, and exploring the DNA exact replication leads to the conclusion.
A colony of bacteria originates from how many bacteria?
All it takes is one bacteria. The cell's divide by binary fission where the microbes DNA splits to form a new cell.
Binary fission differs from mitosis because the new cells?
produced in binary fission are genetically identical clones of the parent cell, while in mitosis, the new cells have the same number of chromosomes as the parent cell but are not always genetically identical due to crossing over and other genetic recombination events.
Is crossing over a process that occurs during mitosis or meiosis?
Crossing over is a process that occurs during meiosis.

What advantage might asexual repoduction by fission have over sexual reproduction?
C
What of these processes produces cells with hereditary information that differs from the parent cell?
The process of meiosis produces cells with hereditary information that differs from the parent cell. Meiosis involves two rounds of cell division that result in the formation of gametes (sperm and egg cells) with unique combinations of genetic material due to crossing over and random assortment of chromosomes.

Are the cells in binary fission alike?
Yes, the cells produced by binary fission are genetically identical to the original cell, as the process involves the replication of the cell's DNA followed by the division of the cytoplasm. This asexual reproduction method is common in prokaryotic organisms, such as bacteria. However, environmental factors or mutations can lead to variations over time, but under normal circumstances, the daughter cells are alike.
Do Viruses multiply through binary fission?
No, they do not. They are hijackers. Once they get attached to the cell of a living cell, they can take it over and "make" the living cell produce virus particles instead of cell parts. These particles can assemble into more viruses and then they break out of the cell (killing it) and begin the process again.No, only living cells divide by binary fission. Viruses are not alive.
How does protozoa reproduce?
Protozoa can reproduce through asexual methods such as binary fission, where the cell divides into two daughter cells, or through sexual reproduction, where genetic material is exchanged between individuals. Some protozoa can also reproduce through multiple fission, budding, or sporulation.
Is crossing over a process that occurs during mitosis or meiosis?
Crossing over is a process that occurs during meiosis.
Is crossing over unique to meiosis?
Yes. Crossover only occurs in prophase of meiosis I. Becuase it does not occur in mitosis, all the cells in our body are supposed to have the same genetic information (of course, excluding the cases where somatic mutations occur, such as in cancer).
Crossing over occurs during which phase of meiosis?
Crossing over occurs during Prophase I of meiosis.
