Good question!
One possible answer lies in some of the benefits that chromosomes have as opposed to genetic sequences that just float around separately. Linked sequences of genes would have had a higher copying fidelity, and there would be a greater certainty that the daughter cell receives, upon cell division, a complete complement of genes necessary for survival. So a tendency for genes (distinct genetic sequences) to link together and form complexes would, under the right circumstances, be favoured. The same pressures may subsequently have lead to the development of telomeric sequences and the distinctive chromatid form.

∙ 16y agoThat is one of the greatest mysteries of of all time. Nobody knows for sure. There are various theories, but not one has been substantiated.

What discovery in the 1900 supported Mendel's ideas?
Chromosomes
How is Eukaryotic DNA organized?
they are grouped into multiple chromosomes.
How do autosomal chromosomes differ from chromosomes?
Autosomal chromosomes are all non-sex (X or Y) chromosomes.
What are haploid chromosomes?
haploid chromosomes are a set of chromosomes from one parent , half the total of diploid chromosomes.
What are the chromosomes that carry the same sets of genes?
Homologous Chromosomes.- for fact.
How do differing numbers of chromosomes evolve without deleterious effects to individuals so that for instance Chimpanzees have 48 chromosomes yet humans have 46?
Chromosomal fusions and chromosomal duplication may lead to decreased or increased numbers of chromosomes with minimal loss of genes.
Why are chromosomes organized into groups?
elements with the same number of valence electrons fall in the same group
What discovery in the 1900 supported Mendel's ideas?
Chromosomes
All chromosomes except the X and Y sex chromosomes are called?
homologous chromosomes and autosomal chromosomes
Humans are a diploid species what does this say about their chromosomes?
They have homologous chromosomes
What best describes chromosomes that contain genes for the same characteristics?
Chromosomes that have the same sequence of genes are called homologous chromosomes.
What are the other 44 chromosomes that are not related to sex called?
The 22 pairs of chromosomes that aren't the sex chromosomes are known as the autosomal chromosomes. The X and Y chromosomes are the sex chromosomes.
How is Eukaryotic DNA organized?
they are grouped into multiple chromosomes.
How do autosomal chromosomes differ from chromosomes?
Autosomal chromosomes are all non-sex (X or Y) chromosomes.
What are haploid chromosomes?
haploid chromosomes are a set of chromosomes from one parent , half the total of diploid chromosomes.
What are chromosomes in?
chromosomes are in cells
What are the chromosomes that carry the same sets of genes?
Homologous Chromosomes.- for fact.
