no
A diploid cell with an extra chromosome. Basically a diploid with an extra chromosome of one type, producing a chromosome number of the form 2n + l.
The condition in which a diploid cell is missing a chromosome or has an extra chromosome is called aneuploidy.
The diploid chromosome number in humans is 46.
yes zygote do have diploid chromosome number
Polyploidy is the condition in which a normally diploid cell or organism acquires one or more additional sets of chromosomes. In other words, the polyploid cell or organism has three or more times the haploid chromosome number. Polyploidy arises as the result of total nondisjunction of chromosomes during mitosis or meiosis.
It is fully diploid - chromosome configuration 2n -.
46
Haploid
it has split in two
A somatic cell with two of each type of chromosome has a diploid chromosome number. This means that the cell has a complete set of chromosomes, one from each parent.
It is fully diploid - chromosome configuration 2n -.
