What term describes a cell with three or more sets of chromosomes?

What is it called when you have multiple sets of chromosomes?

Triploidy is the presence of an additional set of chromosomes in the cell for a total of 69 chromosomes rather than the normal 46 chromosomes per cell. The extra set of chromosomes originates either from the father or the mother during fertilization.

Do chromosomes come in sets of 3?

Humans normally have 46 chromosomes in each cell, divided into 23 pairs. Two copies of chromosome 3, one copy inherited from each parent, form one of the pairs. Chromosome 3 spans about 198 million base pairs (the building blocks of DNA) and represents approximately 6.5 percent of the total DNA in cells.

What is a triploid?

In simple terms, a triploid fish is merely a fish that is sterile. Triploid fish have three sets of chromosomes, unlike a fertile fish that have two sets of chromosomes (a diploid fish). Triploids are common in many industries; Seedless watermelons are triploids, as are bananas. Triploids are also naturally occurring.

What happens if you have 3 extra chromosomes?

Trisomy (‘three bodies’) means the affected person has three copies of one of the chromosomes instead of two. This means they have 47 chromosomes instead of 46. Down syndrome, Edward syndrome and Patau syndrome are the most common forms of trisomy.

Is triploidy compatible with life?

Most fetuses with triploidy do not survive to birth, and those that do usually die within days. As there is no treatment for triploidy, palliative care is given if a baby survives to birth.

Can a human have 3 chromosomes?

“Tri-” is Greek for “three”; people with trisomy have three copies of a particular chromosome in cells instead of the normal two copies. Down syndrome (also known as trisomy 21) is an example of a condition caused by trisomy .

Do chromosomes come in pairs?

Chromosomes come in pairs. Normally, each cell in the human body has 23 pairs of chromosomes (46 total chromosomes). Half come from the mother; the other half come from the father. Two of the chromosomes (the X and the Y chromosome) determine your sex as male or female when you are born.

What is difference between diploid and triploid?

is that triploid is (genetics) having three sets of chromosomes while diploid is (cytology) of a cell, having a pair of each type of chromosome, one of the pair being derived from the ovum and the other from the spermatozoon most somatic cells of higher organisms are diploid.

What is a triploid tissue?

In angiosperms, the endosperm is formed from triple fusion in which male gamete fuses with a diploid secondary nucleus resulting in the formation of a triploid primary endosperm mother cell which then forms the endosperm. Hence endosperm is a triploid tissue.
