How many homologous chromosomes in a haploid organism?
There are no homologous chromosomes in a haploid cell, as a haploid cell has only one set of chromosomes. One member of each pair of homologous chromosomes comes from one set, and the other member comes from the second set, so homologous chromosomes only exist in diploid cells.
Where do chromosomes exist?
they are produced in the nucleus of cells. a human has 23pairs of chromosomes.
After replication how many chromosomes exist?
46 duplicated chromosomes. humans have 23 types of chromosomes (n), each with a homologous pair (1 from mom, 1 from dad) giving us 46 total (2n). When cells undergo replication they duplicate all their chromosomes. The duplicate remains attached to the original chromosome by a centromere. The two attached duplicates are called sister chromatids (this is what you see as an x shaped chromosome- 1 chromosome, 2 sisters) which will be pulled apart during anaphase, giving each cell, once they divide, a full set of 46 chromosomes.
How many chromosomes exist in your body?
A normal human cell contains 23 pairs of chromosomes, for a total of 46. If you had an average of 40 trillion cells in your body that had 412 chromosomes you would have 4456 trillion chromosomes in your body. Note that some mature cells in your body do not have any chromosomes, some have 26 chromosomes and some cells have 99 chromosomes.
Why is chromosomes useful?
Chromosomes are are your genetic material. Without them you would not exist.
How many homologous chromosomes in a haploid organism?
There are no homologous chromosomes in a haploid cell, as a haploid cell has only one set of chromosomes. One member of each pair of homologous chromosomes comes from one set, and the other member comes from the second set, so homologous chromosomes only exist in diploid cells.
How would you know if 2 chromosomes were homologous pairs?
Therefore when two chromosomes of the exact structure exist, they are able to pair together to form homologous chromosomes
If both homologous chromosomes of each pair exist in the same nucleus that nucleus is?
diploid
Where do chromosomes exist?
they are produced in the nucleus of cells. a human has 23pairs of chromosomes.
When do homologues pair?
A homologous pair is a pair of chromosomes that exist in diploid cells. One of the pair you inherit from your father, the other from your mother. A human has 22 pairs of homologous chromosomes (these do not include sex chromosomes). They are the same length and shape. They also share the same genes. The sequences of the genes may be different, which is what results in genetic variation, but the genes are the same.
Each chromosome of a eukaryotic cell consists of a pair of identical structures called?
Chromosomes exist in somatic cells as nearly identical copies of each other called homologous chromosome. The formation of daughter cells that occurs during cytokinesis signals the end of cell division.
Describes an Organism that can exist a group of cells?
Multicellular.
How many chromosomes are in cats diploid cell?
There are 38 chromosomes in a cat's diploid cell. Diploid cells always have an even number of chromosomes because they exist in pairs.
Do all livig things have chromosomes?
Yes all living things, (starting from a cell) have chromosomes. chromosomes are found in DNA and if cells didn't have DNA they wouldn't exist.
Describes an organism that can only exist as a group of cells?
Multicellular.

What describes an organism that can only exist as a group if cells?
the answer is Multicellular! i just figured it out!
