Chromosomes

Chromosomes contain the genetic material DNA

1,309 Questions

What chromosome is in the left testicle?

Well certainly a Y chromosome. XY is the sex chromosomes of males. In male gametes they would be n. That is some sperm would contain a X chromosome that a male would give to a daughter and other sperm would contain a Y chromosome destined for a son.

Does a virus have chromosomes?

No, viruses do not have chromosomes like cells do. They have genetic material in the form of DNA or RNA, but it is not organized into chromosomes.

How many pairs of chromosomes do dragons have?

Dragons are mythical creatures, so they do not have a scientifically determined number of chromosomes. In fantasy depictions, dragons often have a varying number of chromosomes or sometimes possess magical qualities that defy biological norms.

Is google chromosome an internet provider?

No, Google Chromosome is not an internet provider. Google Chromosome is not a service or product offered by Google either. It seems like there may be a confusion between Google Chromosome and Google Chrome, which is a web browser developed by Google.

Are sex chromosomes called homozygous chromosomes?

No, sex chromosomes are not referred to as homozygous chromosomes. Homozygous chromosomes have identical alleles at a specific gene locus, while sex chromosomes determine an individual's biological sex. In humans, sex chromosomes include X and Y chromosomes.

Can chromosomes be repaired?

Chromosomes can undergo repair through mechanisms such as DNA damage response pathways. When a chromosome is damaged, cells can activate repair mechanisms to fix the damage, ensuring proper function and genetic stability. However, severe or unrepaired damage can lead to genetic mutations or cell death.

What happens when a male has xxy sex chromosomes?

A male with XXY sex chromosomes has a condition called Klinefelter syndrome. This can lead to infertility, reduced testosterone levels, and potential physical characteristics like taller height and less body hair. Treatment may involve hormone therapy to alleviate symptoms.

How many chromosomes does a angus bull have?

An Angus bull typically has 60 chromosomes – 30 from the cow and 30 from the bull. Each parental contribution includes 29 autosomes and one sex chromosome (X or Y).

What is an individual with a 48XXXY chromosome pattern?

An individual with a 48XXXY chromosome pattern has an extra X chromosome, resulting in a total of 48 chromosomes instead of the typical 46. This condition is known as Klinefelter syndrome and can lead to developmental and reproductive issues, including infertility and reduced testosterone production. Treatment may involve hormone therapy and support for associated health concerns.

Where chromosomes live?

Chromosomes are found inside the nucleus of a cell, which is typically located towards the center of the cell. They are thread-like structures made of DNA and proteins, and they carry genetic information that determines an organism's traits.

What chromosoMe develops muscle?

Muscle type is polygenic and is probably influenced early on during the gastrulation phase. Since there is substantial variation within families all the alleles are not on the same chromosome.

What chromosome is abnormal in a human karyotype?

An abnormality in a human karyotype can involve any chromosome. Common abnormalities include trisomies (e.g., trisomy 21 in Down syndrome) or monosomies (e.g., Turner syndrome, where an individual is missing an X chromosome). Other abnormalities can include translocations, deletions, or duplications of specific chromosome segments.

What is the chromosome number of an crocodile?

Crocodiles have a chromosome number of 32 pairs, totaling 64 chromosomes.

What pictures of chromosomes help scientist group similar organisms?

Karyotypes, which are images of an organism's complete set of chromosomes, aid scientists in grouping similar organisms based on their genetic similarities and differences. By examining the size, shape, and number of chromosomes in a karyotype, scientists can identify relationships and evolutionary patterns between species. Additionally, banding patterns on chromosomes can provide further insights into genetic relatedness among organisms.

Which chromosome determines a human s sex?

The sex of a human is determined by the presence of two sex chromosomes. Typically, males have one X and one Y chromosome (XY), while females have two X chromosomes (XX). The presence of the Y chromosome determines male development.

What is the role in chromosomes in determining an individuals sex?

Chromosomes play a key role in determining an individual's sex. Typically, females have two X chromosomes (XX), while males have one X and one Y chromosome (XY). The presence of the Y chromosome triggers the development of male traits.

What is the relationships between chromosomes and homologous chromosomes?

Chromosomes are structures that contain genetic information, while homologous chromosomes are pairs of chromosomes that contain similar genes in the same order. Homologous chromosomes are inherited from each parent and undergo processes like crossing over during meiosis to exchange genetic material.

What structures make up chromosomes?

Chromosomes are composed of DNA molecules tightly wound around proteins called histones. This DNA-protein complex is further condensed into chromatin fibers, which then coil and condense to form the recognizable X-shaped structures we see during cell division. Each chromosome contains a single linear DNA molecule that contains the genetic information of the organism.

How do autosomal chromosomes differ from chromosomes?

Autosomal chromosomes are non-sex chromosomes, present in both males and females, while sex chromosomes determine an individual's sex. Autosomes are inherited in pairs, with one copy from each parent, while sex chromosomes come in two types: X and Y. Autosomal chromosomes contain genetic information that determines an individual's traits other than sex characteristics.

How are chromosomes organized?

Chromosomes are organized as thread-like structures made of DNA and proteins. They are found in the nucleus of cells and are divided into regions called genes, which contain the instructions for making proteins. Chromosomes come in pairs, with one inherited from each parent.

Why do some animals have more chromosomes than others?

You do not need to know this information because it could lead to you asking other questions and wondering about the thought of freedom which does not truly exist. Freedom is a state of mind that you are in but your government is bureaucratic holding you so you are in a lying state of communism thus the shrinking bureaucratic class. However textbook communism will be fine if everyone pitches in but greed is a trait of natural human nature and without an enlightened sense we as a group of species will never truly grasp sharing or free will within constrictions.

What are homologous chromosomes and what characteristics do 2 homologous chromosomes share?

Homologous chromosomes are a pair of chromosomes, one from each parent, that have the same genes at the same loci. They share similar genetic information, but may have different versions of the same gene called alleles. Homologous chromosomes also have similar size and structure.

What is the 2n chromosome number of grasshopper?

24 chromosomes are the. 12 from each parent gamate
