Can a person with XO chromosome survive?

User Avatar

Asked by Wiki User

Yes, a person with XO chromosomes can survive. This condition, called Turner syndrome, occurs in about 1 in every 2,500 live female births. While it can lead to various health challenges and fertility issues, many individuals with Turner syndrome can live healthy and fulfilling lives with appropriate medical care and support.

What describes corresponding chromosomes?

User Avatar

Asked by Wiki User

Corresponding chromosomes refer to a pair of chromosomes in which one chromosome is inherited from the mother and the other from the father. They have the same genes at the same positions, known as loci, but may have different alleles for those genes. Corresponding chromosomes are also known as homologous chromosomes.

Why do chromosomes split?

User Avatar

Asked by Wiki User

Chromosomes split during cell division (mitosis or meiosis) to ensure that each daughter cell receives a complete set of chromosomes. This process, called chromosome segregation, allows genetic information to be accurately replicated and transmitted to the next generation of cells.

What contains uncondensed chromosomes that have been duplicated?

User Avatar

Asked by Wiki User

The nucleus of a cell contains uncondensed chromosomes that have been duplicated. During the interphase of the cell cycle, before cell division, the chromosomes replicate and form sister chromatids that are still uncondensed and spread throughout the nucleus.

Does the random sorting of chromosomes during anaphaseII help create unique gametes?

User Avatar

Asked by Wiki User

Yes, the random sorting of chromosomes during anaphase II helps create unique gametes. This process, known as independent assortment, results in different combinations of maternal and paternal chromosomes in each gamete, increasing genetic diversity.

What is a z chromosome?

User Avatar

Asked by Wiki User

The Z chromosome is a sex chromosome found in birds, reptiles, and insects. In species with ZW sex determination, females have two Z chromosomes (ZZ) and males have one Z chromosome (ZW). The Z chromosome plays a role in determining the sex of an individual.

When all the genes of a chromosome have duplicated but are still attached the strutures that are formed are called?

User Avatar

Asked by Wiki User

When all the genes of a chromosome have duplicated but are still attached, the structures that are formed are called sister chromatids. Sister chromatids are identical copies of each other, and they are held together at a specialized region called the centromere.

Where does an organics produced by sexual reproduction get its chromosomes from?

User Avatar

Asked by Wiki User

In sexual reproduction, an organism inherits its chromosomes from both parents. Each parent contributes half of the total number of chromosomes required for the offspring. These chromosomes contain the genetic information necessary for the development and characteristics of the organism.

Which male genotype in the ZW sex chromosome system?

User Avatar

Asked by Wiki User

In the ZW sex chromosome system, the male genotype is ZZ. The letter Z represents the presence of a dominant male-determining gene, while the letter W represents the absence of this gene, which determines female development. Therefore, individuals with the ZZ genotype develop as males in this system.

Why does the y chromosome not carry any alleles?

User Avatar

Asked by Wiki User

The Y chromosome is smaller than the X chromosome and contains fewer genes. It carries the genes necessary for determining male sex and some other genes, but it lacks many of the genes present on the X chromosome. This is why the Y chromosome does not carry any alleles in the same way that the X chromosome does.

Where can you find an image of a chromosome?

User Avatar

Asked by Wiki User

You can find images of chromosomes in scientific research articles, biology textbooks, or on reputable scientific websites such as the National Institutes of Health (NIH) or the Wellcome Trust Sanger Institute websites. Additionally, many educational resources and databases like the Human Genome Project or the Online Mendelian Inheritance in Man (OMIM) also provide images of chromosomes.

Where do chromosomes come from?

User Avatar

Asked by Wiki User

Chromosomes are inherited from our parents. During sexual reproduction, one set of chromosomes is contributed by the mother through the egg cell, and another set is contributed by the father through the sperm cell. When the sperm fertilizes the egg, the resulting zygote carries a unique combination of chromosomes from both parents.

Why did the mutant chromosome got to the tailor?

User Avatar

Asked by Wiki User

There is no specific reason why a mutant chromosome would go to a tailor as chromosomes are found within cells and do not have agency or consciousness to make decisions. The concept of a mutant chromosome going to a tailor is purely fictional and not based on scientific understanding.

Chromosome pairs what and are distributed to sex cells?

User Avatar

Asked by Wiki User

Chromosome pairs undergo a process called meiosis during which they are divided. One of the pairs, known as the sex chromosomes, determines the sex of an individual. In humans, females have two X chromosomes, while males have one X and one Y chromosome. These sex chromosomes are distributed randomly to sex cells during meiosis, resulting in the formation of eggs (in females) and sperm (in males) with varying combinations of sex chromosomes.

Do lobsters have chromosomes?

User Avatar

Asked by Wiki User

A Lobster's body cells do have a nucleus and organelles, hence they are classified as Eukaryotes. Lobsters themselves are properly described on the macroscopic not microscopic scale, and as such the Lobster organism itself doesn't possess a single nucleus; again, the term organelles refers to structures with a cell. On a macroscopic scale the lobster is said to possess organs.
