All organisms, leaving out a select few have to have an even amount of chromosomes because they all sexually reproduce. Therefore when they go through Meiosis and Mitosis they need a even number to reproduce. If there was an odd number in Mitosis then one chromosome instead of 46-23 or 24-12 being evenly split would have to end up being 23-11.5 with a half which isn't possible.

An odd number plus an odd number is what kind of number?
An odd number plus an odd number will be an even number. Odd number A is (even number + 1) Odd number B is (even number + 1) A + B = (even number + 1) + (even number + 1) = even number + even number + 2 Since all even numbers are divisible by 2 and 2 is divisible by 2, each part of the result is divisible by 2, so the sum as a whole is divisible by 2, which means it is an even number.
What numbers between 50 and 60 have an even number of factors?
Every one of them has an even number of factors.
Is 56 odd or even?
An even number can be divided by 2 evenly. An odd number will have a remainder of 1 when divided by 2. 56 is an even number.
Is 26 a odd or even number?
Even. All numbers ending in six are even.
What are all the even numbers less than 1000?
Every second number greater than 2 is an even number.
Why does the body cells of all organisms that reproduce sexually have even numbers of chromosomes?
An animal must have an even amount of chromosomes because, every trait has to have a pair. All chromosomes have to have an even number of chromosomes, otherwise the organisms would not be correctly formed.
Ture or false all organisms have the same number of chromosomes?
False. Different species have different numbers of chromosomes. For example, humans have 46 chromosomes (23 pairs), while dogs have 78 chromosomes (39 pairs).
Why do animals have equal number of chromosomes?
Having an equal number of chromosomes allows for successful reproduction through the process of meiosis, where the number of chromosomes is halved to produce gametes. This ensures that offspring will have the correct number of chromosomes when they receive genetic material from each parent. Having an equal number of chromosomes also promotes genetic diversity through recombination during meiosis.
Do more-complex organisms always have more chromosomes than simpler organisms do.?
Chromosomes contain the genes or the DNA of all organisms. Being more complex, does not mean that you have more chromosomes, for example: a human being has 48 chromosomes while chickens and dogs both have 78.
Can the number of chromosomes in a reproductive cell be greater than the number chromosomes in an organism's body cell?
No. The reproductive cells (eggs, sperm, ova and pollen) all contain half the number of chromosomes of an organisms body cell. This means that at fertilization the two reproductive cells (or gametes) combine to form a single cell with the appropriate number of chromosomes.If a gamete had more chromosomes than a normal cell then fertilization would lead to even more chromosomes and an offspring that would be seriously genetically compromised.
What species other than humans have a haploid number of 23 chromosomes?
Ploidy is another species that has 23 chromosomes. Many organisms have more than two sets of homologous chromosomes.
Did organisms from bacteria to plants to humans have 46 chromosomes?
False not all
A what is a picture of all the chromosomes in a cell?
A karyogram is an image that represents all the chromosomes of a cell that is derived from that organisms organized chromosome profile, or karyotype.
What is a picture of all the chromosomes in a cell?
This is known as a karyogram.
How many chromosomes does a praying mantis have?
All organisms contain 46 chromosomes. A praying mantis will also have 46 chromosomes. The males have 46XX and the females 46XY.
Do All eukaryotic karyotypes contain 46 chromosomes?
No. Different species have different numbers of chromosomes. For example, chimpanzees have 48 chromosomes, domestic cats have 38 chromosomes, and domestic dogs have 78 chromosomes.

How many chromosomes are in the bodycells or an organism that has a haploid number of 8?
The diploid number of chromosomes for an organism with a haploid number of 8 would be 16. This means that in the body cells of this organism, there would be 16 chromosomes, with each chromosome having a pair (homologous chromosomes).
