Reproductive success is defined as the passing of genes onto the next generation in a way that they too can pass those genes on. This allows the survival and successful reproduction of the organisms that are best
suited to their environment; the process that drives evolution known as Natural selection. Asexual reproduction only requires one organism while sexual reproduction requires two organisms; asexually produced cells are genetically identical and sexually produced cells are genetically unique. The genetic variation, or difference
between the generations, provides a very
important advantage to sexually reproducing organisms: the ability to adapt
more quickly to changing conditions in
their environment. Those who reproduce asexually don't need a sexual partner can alone individually
establish a new population in a n
territory.

Mitosis is responsible for reproducing somatic cells and meiosis is responsible for reproducing germ cells. Mitosis duplicates cells DNA and the two daughter cells have the same pieces and genetic code. Two identical copies come from one original meiosis involves not one, but two cell divisions. Second, meiosis leads to the production of germ cells, which are cells that give rise to gametes.
PROPHASE - METAPHASE - ANAPHASE - TELOPHASE - INTERPHASE
This is the phase process for mitosis in which, Prophase : a cell gets the idea that it is time to divide. First, it has to get everything ready. You need to duplicate DNA, get certain pieces in the right position (centrioles), and generally prepare the cell for the process of mitotic division. Metaphase: The DNA lines up along a central axis and the centrioles send out specialized tubules that connect to the DNA. The DNA (chromatin) has now condensed into chromosomes. Two strands of a chromosome are connected at the center with something called a centromere. The tubules actually connect to the centromere, not the DNA. Anapahse: The separation begins. Half of the chromosomes are pulled to one side of the cell; half go the other way. When the chromosomes get to the side of the cell, it's time to move on to telophase. Telophase; This is the time when the cell membrane closes in and splits the cell into two pieces. You have two separate cells each with half of the original DNA.

The Grey Fox reproduces asexually- sperm from the male fertilizes the female’s egg. Both the female and male red fox have specific organs for them to reproduce. The anatomy of the reproductive system of the grey fox is very similar to one of a dog's. The gamete, or egg, is created in the ovary. Once the egg is mature and ready to be fertilized, it travels through the oviduct, where fertilization takes place. The oviduct then branches off into the uterine horn, where the oviduct and uterus meet. The uterus is then where the fertilized egg will develop and grow. The cervix is where the sperm enters the body to fertilize the egg, and the vagina is the external opening out of the body through the genitals. The vagina also contains many layers of mucous, which release mucous to trap bacteria and other harmful particles before they enter the body. (1) The grey fox has 34 chromosomes found in all body cells, which are diploid. In the gametes, there are 17 chromosomes in each cell, which are haploid. (2)
The Zorro is sexually mature at 9-10 months old. The red fox will court by having the males fight with each other to impress the female. This fighting can result in serious injuries, and even death. Most courtship takes place in the winter as well.(3) The red fox spends about 3 months in the womb, and are mature at 7 months old. The red fox has a life expectancy of about 2-3 years as well. A female can have up to 4-6 kits in one litter, and there is extensive parental care. (4)
