How many chromosomes do bony fish have?
nigroviridis genome revealed the basic structure of the ancestral bony vertebrate genome, which was composed of 12 chromosomes, and allowed to reconstruct many of the chromosome rearrangements which led to the modern human karyotype (Jaillon et al, 2004).
How many chromosomes are in a salmon?
European Atlantic salmon generally have 29 pairs of chromosomes and 74 chromosome arms [20], whereas it has been reported that North American Atlantic salmon have 27 chromosome pairs and an NF of 72 [21].
What animal has 32 chromosomes?
American badger
How many chromosomes do tilapia fish have?
These genetic maps established 24 linkage groups although the tilapia karyotype is composed of just 22 chromosome pairs [16].
How many chromosomes do monkeys have?
48 chromosomes
Why do monkeys have more chromosomes than humans?
They have a different number of chromosomes only because one of the human chromosomes is essentially the same as two chimpanzee chromosomes. Either way this would explain why chimps have two more chromosomes than humans. All of this argues that chimps and humans have the same number of genes.
Can a human have 48 chromosomes?
Therefore, humans with XXYY are genotypically male. Males with XXYY syndrome have 48 chromosomes instead of the typical 46. This is why XXYY syndrome is sometimes written as 48,XXYY syndrome or 48,XXYY. It affects an estimated one in every 18,000–40,000 male births.
What happens if a human has 24 chromosomes?
Sequencing all 24 human chromosomes uncovers rare disorders. Extending noninvasive prenatal screening to all 24 human chromosomes can detect genetic disorders that may explain miscarriage and abnormalities during pregnancy, according to a study by researchers at the National Institutes of Health and other institutions.
What happens if you have 22 chromosomes?
Other changes in the number or structure of chromosome 22 can have a variety of effects. Intellectual disability, delayed development, delayed or absent speech, distinctive facial features, and behavioral problems are common features.
What happens if you have 47 chromosomes?
A trisomy is a chromosomal condition characterised by an additional chromosome. A person with a trisomy has 47 chromosomes instead of 46. Down syndrome, Edward syndrome and Patau syndrome are the most common forms of trisomy.
Can a person have 22 chromosomes?
Humans normally have two copies of chromosome 22 in each cell. Chromosome 22 is the second smallest human chromosome, spanning about 49 million DNA base pairs and representing between 1.5 and 2% of the total DNA in cells….

What happens if a human has 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 happens if you have 44 chromosomes?
Unless this chromosome is the X, Y or number 21, the usual result is miscarriage or being born with severe problems. In this case it would almost certainly result in miscarriage. In fact, the 44 chromosome man’s family has a long history of miscarriages and spontaneous abortions.
What happens if you have 2 extra chromosomes?
Cells with one additional set of chromosomes, for a total of 69 chromosomes, are called triploid . Cells with two additional sets of chromosomes, for a total of 92 chromosomes, are called tetraploid. A condition in which every cell in the body has an extra set of chromosomes is not compatible with life.
CAN XXY have babies?
It is possible that an XXY male could get a woman pregnant naturally. Although sperm are found in more than 50% of men with KS3, low sperm production could make conception very difficult.
