One example of an abnormal number of chromosomes in humans is Down syndrome, which results from having an extra copy of chromosome 21. This condition can lead to intellectual disability, distinctive facial features, and other health issues.
An untenable offspring; the death of the fetus. A notable exception is trisomy 21 (25% survive to conception and 85% of those will live to age 1).
One example of an abnormal number of chromosomes in humans is a condition called Down Syndrome. Down Syndrome patients have three copies of chromosome 21 instead of two.

How many chromosomes does every organism has?
Most organisms have a specific number of chromosomes that is characteristic for their species. For example, humans typically have 46 chromosomes (23 pairs), while dogs have 78 chromosomes (39 pairs). However, the number of chromosomes can vary among different species.
How many chromosomes will a gamete of this organism have?
The gamete will have half the number of chromosomes as compared to the somatic cells of the organism. For example, in humans, a gamete will have 23 chromosomes.
Does every species has a characteristic number of chromosomes?
No, different species have different numbers of chromosomes. Humans have 46 chromosomes, dogs have 78 chromosomes, and horses have 64 chromosomes, for example. The number of chromosomes in a species typically remains constant within that species.
Ture or false all organisms have the same number of chromosomes?
False. Different species have different numbers of chromosomes. For example, humans have 46 chromosomes (23 pairs), while dogs have 78 chromosomes (39 pairs).
What is euploid?
Euploid refers to cells or organisms with a chromosome number that is an exact multiple of the haploid number for that species. In humans, the haploid number is 23, so euploid cells would have a total of 46 chromosomes. Euploidy is contrasted with aneuploidy, which involves cells having an abnormal number of chromosomes.

Why a person with Down's syndrome has an abnormal number of chromosomes?
Yes.
What is the species number of chromosomes in humans?
46 Chromosomes
Does every species has a characteristic number of chromosomes?
No, different species have different numbers of chromosomes. Humans have 46 chromosomes, dogs have 78 chromosomes, and horses have 64 chromosomes, for example. The number of chromosomes in a species typically remains constant within that species.
Is twenty-three the haploid number of chromosomes in man?
The twenty-three chromosomes in humans is called a haploid number. It refers to the number of chromosomes in a gamete of an organism.
How many chromosomes does the animal have why?
Animals typically have a specific number of chromosomes characteristic of their species. For example, humans have 46 chromosomes (23 pairs) in most of their cells. Chromosomes contain genetic material, including DNA, which carries the instructions for an organism's development and functions.
What is the diploid number for humans?
2n=46
What is the number of chromosomes per daughter cell after meosis?
After meiosis, each daughter cell has half the number of chromosomes as the parent cell. For example, in humans the parent cell would have 46 chromosomes, but after meiotic cell division, the daughter cells will each have 23 chromosomes.
What type of number is 46 chromosomes in humans?
Its and even number, but probably... having 46 chromosomes would make humans a diploid being
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 is a haploid number of chromosomes?
The haploid number of chromosomes is the number of individual chromosomes in a cell that contains only one set of chromosomes, as opposed to the diploid number which is the full set of chromosomes in a cell. In humans, the haploid number is 23.
