What is the Disjunction of homologous chromosomes to the opposite poles?
During anaphase, the centrosomes (which have moved to opposite poles of the cell) release microtubules from their centrioles which then pull the chromosomes towards them, the double stranded chromosomes then split at the centromere and thus each pole of the chromosome has a copy of every chromosome.
I assume you're talking about meiotic division though and in this case the spindle fibres/ microtubules dont split the chromosomes in half, rather, the chromosomes line up in homologous pairs (instead of in single file) and the spindle fibres pull one of the entire homologous double stranded chromosomes to its designated pole.
Where is the chromosome's located?
In a human cell the chromosomes are found in the nucleus. In bacteria and other prokaryotic cells the chromosomes are found floating freely in the cytoplasm.
How many chromosomes produce meiosis?
It produces four genetically different cells with 23 chromosomes each. They are haploid.
What chromosome is affected in fabry disease?
The allele that is responsible of Fabry Disorder/Disease is located on the X chromosome and is the only lipid storage disorder identified as being sex linked.
What is mirroring chromosomes?
Mirroring chromosomes are a genetic abnormality. This abnormality is caused by an exact duplication of a chromosome segment, including the centromere.
Impossible to count individual chromosomes?
It is not impossible to could individual chromosomes. There is a test that can count them.
What happens to the remaining chromosomes from the last division in meiosis?
In meiosis all the chromosomes are incorporated into sperm cells whereas production of an unfertilized egg results in the leftover chromosomes incorporated into polar bodies.
Can a sperm cell contain maternal chromosomes?
Absolutely (assuming you are referering to the maternal chromosomes of the man who is making the sperm) , the human set of chromosomes is composed of 46 pairs with half (23) coming from each parent. Mendel's laws suggest that each chromosome segregates and separates independently during mitosis (and subsequently meiosis) thus each gamete should contain a mixture of paternally and maternally derived chromosomes.
What does it mean when someone has an extra chromosome?
If someone has an extra chromosome it means there was a genetic mutation that is abnormal in human development. It may result in problems with the person affecting them on a basic level, or may go fully unnoticed. A common disorder that can be caused by having an extra chromosome is Down's Syndrome.
What phase does the chromosomes become invisible?
Interphase also known when you have fun with yourself
What is congression of chromosomes?
movement of chromosomes to spindle equator during mitosis is also known as congression of chromosomes.
Why are chromosome copied before mitosis?
After Mitosis, the result is 2 new, identical, daughter cells. In order for each to be identical, the chromosomes must be copied.
Depending on their relative location on the chromosome the alleles will remain on the same chromosome or be separated in the crossing over part of meotic divsion. The closer they are to each other the more likely they will stay together.

What do you call chromosome that look alike and carry genes for the same trait?
Chromosomes that look alike and carry genes for the same trait are called homologous chromosomes. The nucleus contains these chromosomes.
In als what chromosome is affected?
In ALS, also known as amyotrophic lateral sclerosis, the chromosome primarily affected is chromosome 9. A gene called C9orf72 located on this chromosome is linked to a significant percentage of familial ALS cases. Other genetic mutations on different chromosomes can also contribute to ALS development.
How many chromosomes did Homo neanderthal have?
I am willing to bet it's 48, unlike 46, which humans have.
All apes have 48 chromosomes, including chimps, gorillas, orangutans, australopithecines, early homos (erectus, neanderthals etc).
Humans have 46 chromosomes and are unique among apes because humans (homo sapiens) are only 150 - 200.000 years old (according to mitochondrial DNA) and were created using genetic engineering by an advanced human-like race that visited Earth in the distant past.
The advanced beings used their own DNA and the DNA of apes such as neanderthals to create us so that we would be inferior version of them (aliens) which were better adapted to this planet than they were.
They were also the ones to teach us civilization and we owe our knowledge and advancement to them!
