Chromosomes

The 'body' cells have 42 chromosomes. The sex cells would have 21 chromosomes.

A carp cell typically contains 100 chromosomes. This is because carps are polyploid organisms, meaning they have multiple sets of chromosomes.

Chromosomes in bacteria cells carry the genetic information necessary for the cell to function and reproduce. They contain the bacterial DNA in a single circular structure, and are essential for controlling the cell's growth and metabolism.

Homologous chromosomes are pairs of chromosomes containing genes for the same traits at the same locations, one inherited from each parent. During meiosis, homologous chromosomes separate and recombine to create genetic diversity in offspring. They help ensure that the proper number of chromosomes is passed on to the next generation.

No, Parkinson's disease is not caused by a mutation on chromosome 6. The exact cause of Parkinson's disease is not fully understood, but it is believed to involve a combination of genetic and environmental factors. Some rare forms of Parkinson's disease are linked to specific gene mutations, but these are not located on chromosome 6.

Killer whales have a total of 44 chromosomes, which consist of pairs of chromosomes inherited from each parent. This includes 22 pairs of autosomes and one pair of sex chromosomes, either XX for females or XY for males.

The technique for visualizing maize chromosomes was developed by Barbara McClintock, an American geneticist who conducted groundbreaking research on maize genetics in the early to mid-20th century. Her work led to the discovery of transposable elements or "jumping genes" in maize chromosomes, for which she was awarded the Nobel Prize in Physiology or Medicine in 1983.

Seals typically have a diploid number of 34 chromosomes. This means they have 17 pairs of chromosomes in their cells.

^Incorrect.

I assume you're talking about humans, in which case a healthy child will have 46 chromosomes. There are 22 pairs of autosomal chromosomes and the 2 sex ones (XX or XY).

I believe that they use something called karyotyping. The scientist will basically get some tissue samples from your body and let it grow in their lab. Then another will take this sample and look under a microscope to examine the shape, size and will count the amount of chromosomes that are present in the cells. They will then proceed and take a picture of the chromosomes.

Genes on the Y chromosome are responsible for male sex determination and other male-specific traits. They play a crucial role in the development of male reproductive organs and secondary sexual characteristics.

there are 8 chromosomes in an adult house fly.

Any chromosome can be affected by changes in chromosome numbers. This can include trisomy (three copies of a chromosome), monosomy (one copy of a chromosome), or other abnormalities such as deletions or duplications. These changes can lead to genetic disorders or abnormalities.

The rules were worked out in the middle years of the nineteenth century by an Austrian monk named Gregor Mendel, who devised them after conducting an extensive series of experiments on garden peas.

Humans have 23 pairs of chromosomes. Males have 1 X chro. and 1 Y chro. in a pair. Females just have 2 X's. The first 22 pairs are evenly spaced between male and female, but the 23rd depicts which gender you are.
Chromosomes are an important part of your DNA.

An example of homologous chromosomes in humans is the pair of chromosome 1 from each parent. Homologous chromosomes carry similar genes in the same order, although they may have slight variations in the actual DNA sequences.

High methylation of a chromosome typically leads to gene silencing, as it can inhibit the binding of transcription factors and RNA polymerase needed for gene expression. This can result in decreased or altered gene activity, impacting cellular functions and potentially leading to various diseases or abnormalities.

4 because the parent cell has four chromosomes arranged in 2 pairs. Each offspring has 4 chromosomes, one pair from each parent.

Having two X chromosomes typically results in a person being biologically female. This genetic combination allows for the development of typically female physical characteristics, although exceptions and variations do exist.

After chromosomes condense during cell division, they align along the center of the cell during metaphase. During anaphase, the sister chromatids separate and move towards opposite poles of the cell. Finally, during telophase and cytokinesis, the cell divides into two daughter cells, each with a complete set of chromosomes.

A karyotype shows chromosomes arranged by size, shape, and banding pattern. This arrangement helps to identify any structural abnormalities or genetic disorders by comparing the individual's chromosomes with a standard karyotype.

No, prokaryotic chromosomes only comprise of one chromosome.

An X chromosome is much, much larger than a Y chromosome. For this reason, an X chromosome is more important for life than a Y. Let's consider the options you posed:

YY --> because the Y chromosome is so small, there is not enough genetic information for an organism to survive. This is not viable and will not even form an organism.

YYY --> again, same thing. See above.

XXY --> Klinefelter's syndrome. This produces a male with an inhibited reproductive ability; he will probably not be able to produce offspring.

XXX --> Triplo-X syndrome. Because in normal females, one X chromosome is turned off anyways (Barr body) to avoid any extra genetic info, the same thing happens here, only both X chromosomes are turned off. Only one X chromosome is active at a time. There's no distinguishable difference between XX and XXX females.

XYY --> Normal male. Most men who have this genotype probably don't even know they have it.

There are no 'Side Effects', just things that 'come with the package'.

You can suffer breathlessness, bowel problems and probalmes with liver and kidneys. There are other things too, but at age 13, that's all I've really had so far.
