How many chromosomes does a monoatomic plant have? Cells that have one extra set of chromosomes, for a total of 69 chromosomes, are called triploids. Cells that have two extra sets of chromosomes, totaling 92 chromosomes, are called tetraploids. A condition in which every cell in the body contains an extra set of chromosomes that are incompatible with life.
How many chromosomes are in the mononuclear cell? What are monosomies? The term “monosomy” is used to describe the absence of one member of a pair of chromosomes. Therefore, there are 45 chromosomes in each cell of the body instead of the normal 46 chromosomes.
How many chromosomes are in a plant? Questions 122 – 125: If the number of diploid chromosomes of a flowering plant is 24, then the somatic cells of the plant contain 24 chromosomes (12 chromosomes from the mother and 12 from the father).
How many chromosomes does a triploid have? Polyploidy is the presence of an extra set of chromosomes in a cell for a total of 69 chromosomes instead of the normal 46 chromosomes per cell. The extra set of chromosomes arises from either the father or the mother during fertilization.

What happens if you have 50 chromosomes?
These results demonstrate that primary hyperploidy (over 50 chromosomes) is an independent favorable prognostic marker in childhood, and additional chromosomal structural abnormalities may not indicate a poor prognosis among hyperploid children (over 50 chromosomes).
What happens if you have 48 chromosomes?
48, XXYY syndrome is a chromosomal condition that causes infertility, developmental and behavioral disorders, and other health problems in males. 48, XXYY disrupts male sexual development.
What human possesses the most chromosomes?
In a recent article, a doctor in China identified a man with 44 chromosomes instead of the normal 46. Except for the different number of chromosomes, this guy is completely normal in every measurable way.
Which organism has the most chromosomes?

What if a person has 47 chromosomes?
Trisomy is a chromosomal condition characterized by the presence of an extra chromosome. A person with trisomy has 47 chromosomes instead of 46. Down syndrome, Edwards syndrome, and Patau syndrome are the most common forms of trisomy.
What happens if you have 69 chromosomes?
Three sets, or 69 chromosomes, are called triploids. Typical cells contain 46 chromosomes, 23 of which are inherited from the mother and 23 from the father. Triploidy occurs when a fetus receives an extra set of chromosomes from one parent. Triploidy is a fatal condition.
Are bananas triploid?
For example, the common banana is triploid. In other words, it has three sets of chromosomes. Instead of getting one set of chromosomes from each parent, it has two sets from one parent and one set from the other parent. The banana, too, is a reproductive plant, producing fruit in the absence of successful fertilization.
What happens if you have 3 extra chromosomes?
The common form of aneuploidy is trisomy, or the presence of an extra chromosome in cells. “Tri-” is a Greek word meaning “three”; People with trisomy have three copies of a particular chromosome in their cells instead of two normal copies. Down syndrome (also known as trisomy 21) is an example of a condition caused by trisomy.
Can a human have 50 chromosomes?
Normal human cells normally contain 23 pairs of chromosomes; However, cancer cells can contain 50 or more chromosomes. To specifically diagnose the underlying cause of aneuploidy and also to specifically target or treat aneuploidy, one has to understand the causes of aneuploidy in the first place,” added Dr. Draviam.
Can a human have 48 chromosomes?
The appearance of at least one Y chromosome with a properly functioning SRY gene makes a male. Therefore, humans with XXYY are genetically male. Males with XXYY syndrome have 48 chromosomes instead of the typical 46. This is why XXYY syndrome is sometimes written as 48, XXYY or 48, XXYY.
What happens if humans have 24 chromosomes?
Sequencing of all 24 human chromosomes reveals rare disorders. Expanding noninvasive prenatal screening to all 24 human chromosomes could detect genetic disorders that may explain miscarriages and abnormalities during pregnancy, according to a study by researchers at the National Institutes of Health and other institutions.
Can a person have 56 chromosomes?
It doesn’t matter whether the human genes are in 46 or 56 chromosomes – it’s the genes that matter. A large set of numbers of chromosomes. Animal chromosome numbers range from 254 in hermit crabs to 2 in a type of roundworm. A fern called Ophioglossum reticulatum has 1,260 chromosomes!
What happens if you have 49 chromosomes?
Syndrome 49, XXXXY is a chromosomal condition in boys and men that causes intellectual disability, developmental delays, physical differences, and the inability to have biological children (infertility). Its signs and symptoms vary between affected individuals.
What happens if you have 45 chromosomes?
There are two types of Turner syndrome: monosomy X TS and mosaic TS. About half of girls with Turner syndrome have a monomicroscopic disorder. Monosomy means that a person is missing one chromosome in a pair. Instead of 46 chromosomes, a person has only 45 chromosomes.
Can a female XY get pregnant?
Males and most XY females cannot get pregnant because they do not have a uterus. The uterus is where the fetus grows, and pregnancy is not possible without it. In most cases, the presence of the Y chromosome means that there is no uterus, so pregnancy is not possible.
Can XXY have children?
It is possible for an XXY male to conceive a woman naturally. Although sperm is present in more than 50% of men with KS3, low sperm production can make conception very difficult.
Can you live without a chromosome?
Yes, but there are usually health problems associated with it. The only case in which a missing chromosome is tolerated is when an X or a Y chromosome is missing. This condition, called Turner syndrome or XO, affects about 1 in 2,500 females.
What is 23 chromosomes called?
Twenty-two of these pairs, called autosomes, look alike in both males and females. The twenty-third pair, the sex chromosomes, differs between males and females. Females have two copies of the X chromosome, while males have two copies of the X chromosome and one Y chromosome. 22 autosomes are numbered by size.
What animal has the largest number of chromosomes?
Mitotic and meiosis chromosomes of the semi-aquatic rodent Ichthyomys pittieri (Rodentia, Cricetinae) from Venezuela were analyzed by conventional staining and several banding techniques. The diploid chromosome number of this rare species is 2n = 92, which is the highest value known to mammals.
Could you be a girl with an XY chromosome?
The X and Y chromosomes are called “sex chromosomes” because they contribute to how a person’s sex develops. Most males have XY chromosomes and most women have XX chromosomes. But there are girls and women who have XY chromosomes. This can happen, for example, when a girl has androgen insensitivity syndrome.
