The "rate" of evolution is most accurately gauged in terms of divergence between genetic sequences. Chromosomes are basically groupings of such sequences. It is certainly possible that the number and order of these groupings affect future developments (for instance: polyploidy and chromosomal fusions can affect speciation events), but they do little to affect the overall "rate" of divergence.
What else can I help you with?
Do all species have the same number of chromosomes?
No, chromosomes vary from species to species. A species is distinguished by individuals that can mate and have young that are capable of producing offspring. The number of chromosomes two individuals have must be the same for this to be possible.
Do Different Eukaryote organisms have different amount of Chromosomes?
Yes, different eukaryotic organisms can have different numbers of chromosomes. For example, humans have 46 chromosomes, while corn plants have 20 chromosomes. The number of chromosomes can vary widely among eukaryotic species.
How many chromosomes does every organism has?
Most organisms have a specific number of chromosomes that is characteristic for their species. For example, humans typically have 46 chromosomes (23 pairs), while dogs have 78 chromosomes (39 pairs). However, the number of chromosomes can vary among different species.
If two organisms have the same full set number of chromosomes are the always members of the same species?
Not necessarily. While many members of the same species may have the same number of chromosomes, it does not guarantee that two organisms with the same number of chromosomes are of the same species. Chromosome number is just one characteristic used to define species, but other factors like genetic makeup, morphology, and ability to reproduce with one another are also important in determining species classification.
List of number of chromosomes present in different plants and animals?
Different animals have different numbers of chromosomes. Humans have 46 chromosomes while other animals vary in the amount of chromosomes. A pig has 38 and a horse has 64. Was there as specific animal that you wanted to know about?

How many chromosomes do snakes have?
Snakes have 74. The amount of Chromosomes may vary with different species of snakes.

Compare and contrast adaptation vs evolution?
Adaptation is a mechanism of evolution. It occurs in relatively short period of time among individuals or groups of individuals. Evolution takes a longer amount of time and encodes changes in the DNA of a species.
Why do potatoes have more chromosomes than humans?
The number of chromosomes of a species has little to do with the complexity of the organism or the amount of DNA. The reason for this is, chromosomes are known to break and form two or more new chromosomes, or fuse into one. The chromosomes of the potato and the potato lineage may have undergone many such changes, and the human lineage may have undergone a different series, resulting in the potato having more chromosomes.
What is the number of chromosomes in a cell made through mitosis?
Double the amount it starts with because its replicating itself
What is fixity of species?
Fixity of species is a term which means all species remained unchanged throughout the history of the earth. This belief is generally not accepted by the majority in present times because of the vast amount of evidence supporting evolution.

What is the total amount of chromosomes do down syndrome children have?
21 chromosomes
In phases of mitosis how many chromosomes does the parent cell have during prophase at the start of mitosis?
During prophase at the start of mitosis, the parent cell has a diploid number of chromosomes, which consists of a complete set of chromosomes from both parents. This means that if a human cell has 46 chromosomes prior to mitosis, it would have 46 chromosomes during prophase as well.
