Chromosomes

Chromosomes contain the genetic material DNA

1,309 Questions

What is the definition for chromosomes?

Chromosomes are thread-like structures made of DNA and proteins that contain the genetic information of an organism. They are found in the nucleus of a cell and are responsible for carrying and passing on hereditary traits from one generation to another. Humans typically have 46 chromosomes organized into 23 pairs.

How is sex determined in a person with a chromosomal disorder involving the sex chromosomes?

The specific chromosomal disorder will determine how sex is determined. For example, in Klinefelter syndrome (XXY), the individual typically presents as male, while in Turner syndrome (XO), the individual typically presents as female. These disorders can result in a variety of physical and developmental differences related to sex characteristics.

What part of a cell is a chromosome found?

Chromosomes are found in the nucleus of a cell. They are structures that contain the genetic material of the cell in the form of DNA.

Why are sex chromosomes important?

Sex chromosomes determine an individual's sex and play a crucial role in sexual development and reproduction. They carry genes that influence various physical and physiological traits related to sex, such as secondary sexual characteristics. Additionally, they are responsible for genetic diversity and the inheritance of sex-linked disorders.

How do Sutton's observations about chromosome support the chromosome theory of inheritance?

Sutton's theory is that chromosomes have something to do with the inheritance of traits of their parents. His observation is that grass hoppers have 24 chromosomes but their sex cells only have 12

Where do you inherit chromosomes from?

Chromosomes are in the sperm, one sperm is either a female or male, its also in your dna once you've been "made"

Is a chromosome a allele?

No, a chromosome is a structure that contains genetic information, while an allele is a specific variant of a gene located on a chromosome. Chromosomes contain many alleles that determine an individual's traits and characteristics.

Is a triploid chromosome viable in humans?

Triploid chromosome (69 total chromosomes instead of 46) is not viable in humans and typically results in miscarriage. It is considered a lethal condition due to the abnormal number of chromosomes, which disrupts normal genetic function and development.

What does a cell chromosome relate to in a school?

A cell chromosome is similar to a school's schedule. Just like how chromosomes contain the genetic information and instructions for a cell, a school schedule outlines the classes, activities, and timelines for students. Both help organize and regulate the functioning of the cell or school.

What are the total chromosomes of a normal person?

A normal person has 23 chromosome pairs. (22 autosomes, and 1 sex chromosome that is either XX or XY) If counting each individual chromosome, a normal person has 46.

What represents the body chromosomes?

Chromosomes are thread-like structures made of DNA and proteins that contain the genetic information (genes) of an organism. They are found in the nucleus of cells and come in pairs - one inherited from each parent. Chromosomes are crucial for cell division, growth, and development.

Where in the body do you find chromosome?

Chromosomes are found in the nucleus of cells. They are made of DNA and contain the genetic information needed for an organism to develop, grow, and function. Each human cell typically has 23 pairs of chromosomes.

When do chromosome form?

Chromosomes form during cell division, specifically during mitosis and meiosis. They condense from chromatin (the relaxed form of DNA) into distinct structures that can be easily segregated into daughter cells. This process ensures that each daughter cell receives the correct number and type of chromosomes.

Is it normal to get more pleasure durning sex when being choked?

Well, it's not exactly "normal," but that doesn't mean it's a bad thing. Some people are aroused by choking, and as long as it's done carefully it's all right. But -- and this is important -- be sure you and your partner know exactly what you're doing. It's possible to permanently injure your larynx; oxygen deprivation can cause permanent brain injury, and even death. Please play carefully (and it wouldn't hurt to take a first aid course)!

What combination of sex chromosomes represents a normal female genotype?

A normal female genotype typically has two X chromosomes, represented as XX. These chromosomes determine the female sex characteristics and reproductive system development.

How many chromosome do coconut trees have?

Coconut trees have 32 chromosomes, which is typical for most varieties. These chromosomes are found in the cells of the coconut tree's nucleus.

What complications could occur if male and female sex chromosomes were XY?

This can occur in a very rare condition where genetically the baby is a boy (XY), but during that time of sexual determination (7th week of the pregnancy), the testosterone gene is not turned "on" making the XY baby not a boy but a fully functional girl.

If this fully functional XY girl meets up with a XY boy and they decide to have children, this is what might happen:

XY x XY

  • XX = girl baby - 25% probability
  • XY = boy baby - 50% probability
  • YY = lethal gene -- miscarriage - 25% probability

Does the inheritance theory suggests genes are located on chromosomes in exact locations?

Yes, the inheritance theory suggests that genes are located on chromosomes in specific locations called loci. Genes are segments of DNA that provide the instructions for building proteins and controlling various traits, and their precise positions on chromosomes can impact inheritance patterns.

Which gamete has the chromosome that determines a person's sex?

The sperm gamete carries either an X or a Y chromosome, which determines the sex of the offspring. If the sperm carries an X chromosome, the offspring will be female, while if it carries a Y chromosome, the offspring will be male.

What kind of chromosome does bacterium have?

Bacteria typically have a single, circular chromosome that is not contained within a nucleus. This chromosome carries the majority of the bacterium's genetic material and is essential for the organism's survival and reproduction.

How are chromosomes in bone cells different from the chromosome in skin cell?

They are very similar; they both have 22 pairs of chromosomes but the difference lies in the fact that the man has 2 unpaired chromosomes 1 X and 1 Y. Whereas the woman has a pair of X chromosomes and no Y chromosomes.

Where did you get your chromosome?

one of your parents each give a chromosome

Why does a single sperm have only one sex chromosome?

A sperm cell contains either an X or Y sex chromosome, determining the biological sex of the offspring when combined with an egg. This ensures that the resulting embryo will have the proper number of sex chromosomes (XX for female or XY for male) to develop into a healthy individual.

What would a male with the sex chromosomes xxy have?

A male with the sex chromosomes XXY would have Klinefelter syndrome, a genetic condition that can result in low testosterone, reduced fertility, and other possible physical and developmental traits.
