homologous chromosomes are chromosomes where both alleles are the same, either both dominant or both recessive.

∙ 13y agoA chromosome is a structure containing DNA and various proteins in a nucleus. The proteins help organize and regulate the DNA molecule. The name literally means "colored body" referring to the fact that certain dyes bind to DNA and can be used to stain the chromosomes.
Note: scientific literature oftentimes refers to other forms of DNA molecules as chromosomes (which more correctly may be called plasmids, genophores, etc.).

∙ 9y agoA chromosome is packaged and organized chromatin, a complex of macromolecules found in cells, consisting of DNA, protein and RNA. The main information-carrying macromolecule is a single piece of coiled double-stranded DNA, containing many genes, regulatory elements and other non-coding DNA. The DNA-bound macromolecules are proteins, which serve to package the DNA and control its functions

chromosome.
What is a small circular segment of DNA found in many bacteria but separate from the bacterial chomosome?
The small circular segment of DNA is called plasmid.
Identify 3 causes of chromosomal disorders?
-late pregnancy made the baby inside the mother have a higher risk of getting Down Syndrome -Electromagnetic waves like UV light or X-ray cause our chomosome to mutate -Family inheritence
What is allopolyploidy?
Allopolyploidy is when a fertile organism has more than two chromosome sets due to two different species interbreeding and combining their chromosomes. Allopolyploids are fertile when they breed with each other but cannot breed with either of their parent species so they are now considered a new biological species. Triticale, a hybrid of wheat and rye, is an allopolyploid with six sets of chromosomes. Amphidiploid is synonymous with alloploid.
Can girls be colour blind?
Yes but it is more likely in males. The reason for this is women have two X chromosomes, and men have one X and one Y chromosome. The gene for color sight is found on the X chromosome. If a woman has a defective gene on her X chromosome, she has another to back it up. If a man has a defective gene on his X chromosome, he does not. Both X chromosomes have to be defective in the same way for a woman to be color blind, which is the reason why it is so rare. Male colorblindness, on the other hand, is quite common because the gene is not necessary and therefore the people with it don't get weeded out of the Gene Pool. If a necessary gene is defective, you die, and it does not get passed on. It has to mutate again.
Is chomosome found in plant or animail cell?
both. chromosomes are made of dna. they carry the genetic information of the cell

How many of sex chomosome and autosome are in a human somatic cell?
44 autosomes and 2 sex chromosomes are present in human somatic cells .
Why is it important for the chomosome to make copies of themselves BEFORE mitosis occurs?
Because it has to duplicate itself before it goes through the process of mitosis.
How does the structure of DNA allow the molecule to store information?
it is made up by chomosomes which is the dna sequence and takes place in every cell you have. but if one of the chomosome is missing it can make the person mutate

What are the specific names of autosomal chromosomes like sex chromosomes?
Y chromosome is autosomal dominant chromosome. When it is present, the sex of the child is male. When both the chromosomes are X, then the sex of the child is female. X chomosome is called as autosomal recessive chromosome.

What happens when the recessive allele is passed on to a boy?
Based on your history, you are probably talking about colorblindness, which is a disease inherited on the X chromosome. When it is passed on to a boy, the recessive allele shows itself because boys only have one X chromosome. Edited answer: Though recessive alleles do not express but if it adds to a deficiecy it is reflected in the boy, because only one X chromosome in present there, the other being Y chomosome which is almost enert.
What are chomosome?
Chromosomes are organized structures of DNA and proteins that are found in cells. A chromosome is a singular piece of DNA, which contains many genes, regulatory elements and other nucleotide sequences. Chromosomes also contain DNA-bound proteins, which serve to package the DNA and control its functions. The word chromosome comes from the Greek χρῶμα (chroma, color) and σῶμα (soma, body) due to their property of being stained very strongly by some dyes.
How does hemophilia progress?
Hemophilia is a recessive allele condition. Men can get hemophilia alot easier than women as the allele is found on the XY Chomosome pair. With men. they do not have the extra "tail" on the Y chromosome compared to the XX with a female. If the person has the recessive allele on the X chromosome and this person is male, they will be a hemophiliac as they do not have a 'pair' allele which could be dominant to stop the condition expressing itself. On a female, if there is a recessive (hemophilia) allele on one of the X chromosomes but on the other is a Dominant (normal) allele then she will be a carrier of the faulty gene but will not suffer from the condition herself. If the female have a recessive (faulty) gene on each of the XX chromosomes, then she will be a sufferer of the disease.
