How many chromosomes would a monosomal plant have? Cells with an extra set of chromosomes, i.e. a total of 69 chromosomes, are called triploid. Cells with two extra sets of chromosomes, for a total of 92 chromosomes, are called tetraploid. A state in which every body cell has an extra set of chromosomes is incompatible with life.
How many chromosomes are in a monosomal cell? What are monosomies? The term “monosomy” is used to describe the absence of one member of a chromosome pair. Therefore, there are 45 instead of the usual 46 chromosomes in every body cell.
How many chromosomes does a plant have? Questions 122-125: If the diploid chromosome number of a flowering plant is 24, then the somatic cells of the plant each contain 24 chromosomes (12 maternal and 12 paternal).
Readers Ask: How Much Does It Cost to Install a Fan in a Bathroom?How many chromosomes does a triploid have? Triploidy is the presence of an extra set of chromosomes in the cell, totaling 69 chromosomes instead of the normal 46 chromosomes per cell. The extra set of chromosomes comes from either the father or the mother during fertilization.

What happens when you have 69 chromosomes?
Three sets or 69 chromosomes are called a triploid set. Typical cells have 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 of the parents. Triploidy is a deadly condition.
Is banana a triploid?
For example, the common banana is triploid. In other words, it has three sets of chromosomes. Instead of having one set of chromosomes from each parent, it has two sets from one parent and one set from the other parent.

A common form of aneuploidy is trisomy, or the presence of an extra chromosome in cells. “Tri-” is Greek for “three”; People with trisomy have three copies of a particular chromosome in their cells instead of the normal two 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 have 23 pairs of chromosomes; However, cancer cells can have 50 or more chromosomes. In order to specifically diagnose the underlying cause of aneuploidy, and also to target or treat aneuploidy, one needs to understand what causes aneuploidy in the first place,” Draviam added.
Can a human have 48 chromosomes?
Having at least one Y chromosome with a properly functioning SRY gene makes a male. Therefore, people with XXYY are genotypically male. Men with XXYY syndrome have 48 instead of the typical 46 chromosomes. This is why XXYY syndrome is sometimes written as 48,XXYY syndrome or 48,XXYY.

Can an XY woman get pregnant?
Men and most XY women cannot get pregnant because they don’t have a uterus. It is in the womb that the fetus develops, and without it, pregnancy is not possible. In most cases, having a Y chromosome means you don’t have a uterus, making pregnancy impossible.
