Sexual and Asexual Reproduction

Sexual and Asexual reproduction both are attempting to accomplish the same thing but they are just doing it in different ways

Sexual Reproduction is the creation of an offspring by fusion of males sperm and a females egg. With sexual reproduction it wont create an exact copy because it is taking the DNA from both parent cells. Doing it this way you can have immunity to diseases that would have affected your ancestors.

Asexual reproduction is creating an offspring but without the fusion a males sperm and a females egg. It is just one of the parents offspring`s and there is no fusion of gametes. The offspring is basically cloned because everything about it is the exact same. The number of chromosomes almost never changes with asexual reproduction. A big downside to asexual reproduction is the fact that when the offspring is made, it is susceptible the all of the same diseases as the parent cell, so they are more likely to get damaged by one type of bacteria or sickness. It is susceptible to the same diseases because they don`t evolve at all, they are just complete copies that never change 

 

What are the differences between mitosis and meiosis?

Mitosis produces two daughter cells with the same amount of chromosomes as the parent cell. Meiosis on the other hand produces 4 daughter cells that only contain half of the parent cells. Mitosis is done by 2 parent cells and Meiosis is done independently. With mitosis the cell evolves and is never identical to either parent cell since it is a mix of both of their DNA.  Meiosis is a complete replica of the parent cell so it never changes and will never evolve or develop resistance to certain illnesses or diseases that the parent cell wasn’t resistant to either. Meiosis has more steps than mitosis because it has 8 different steps and mitosis only has 5.

 

First thing is Interphase, it is when DNA is duplicated and spindle fibers are formed. The next step is prophase, it is when the chromatids pair up. Next is Metaphase and it is when the chromosomes line up on the equator of the cell. The next and final stage for mitosis is telophase, it forms 2 new nuclear membranes and separates the center of the cell creating an identical new wall and splitting the cell into 2 different cells and ending the process.
