First, prophase this is when the chromosomes are just chillin in the nucleus that is protected by the nuclear envelope(the purple circle in the blue circle).
Then, metaphase this is when the nuclear envelope breaks down and the chromosomes line up on the metaphase plate in a line.
Then, anaphase this is when the two chromatids that make up one chromosome are pulled apart by spindles.
Then, telophase this is when the spit chromatids start to form new nucleus and causing the cleavage furrow, the line in between the cells that holds them together, to form.
Finally Cytokinesis, this is where you finally get your too new cells.
No because the offspring has a 50/50 chance of having black fur x
Two ways:
1. In prophase I of meiosis the homologous chromosomes synapse and crossing over occurs. This switches sections of two of the sister chromatids so the outer two chromatids have the same mix of alleles as the parents and the inner two chromatids have new combinations of alleles.
2. Meiosis puts only one of each kind of chromosome in the gametes, selecting one of each homologous pair at random. Then when each gamete joins with the gamete from the other parent, there are practically infinite combinations of the alleles possible.

Explanation:
Deoxyribonucleic acid (DNA) and Ribonucleic acid (RNA) are perhaps the most important molecules in cell biology, responsible for the storage and reading of genetic information that underpins all life. They are both linear polymers, consisting of sugars, phosphates and bases, but there are some key differences which separate the two1. These distinctions enable the two molecules to work together and fulfil their essential roles. Here, we look at 5 key differences between DNA and RNA. Before we delve into the differences, we take a look at these two nucleic acids side-by-side.
