What is tetraploid?
An organism is tetraploid if each autosomal cell contains 4 copies of each chromosome.
How many chromosomes would a tetraploid potato gametic cell contain?
The gamete would contain half the number of chromosomes as the tetraploid parent cell.
What might happen if cytokinesis were omitted from the cell cycle?
If it is skipped the cell does not finish division and will then have at least two nuclei.Cytokinesis failure leads to both centrosome amplification and production of tetraploid cells, which may set the stage for the development of tumor cells.However, tetraploid cells are abundant components of some normal tissues including liver and heart. In humans, the number of polyploid cells averages 30–40% in the adult liver.
Can a fertilized egg survive if it has ninety two chromosomes?
From the category the question was placed in I assume you meant a human egg cell. In which case, the short answer is no. The longer version would be that a tetraploid zygote might survive for a while but it will not make it through the embryonic stage. The fetus will not form, the embryo will not survive that long.
How many chromosome in wheat?
Wheat of the species Triticum aestivum (bread wheat), is hexaploid, with 42 chromosomes. Durum wheat, Triticum turgidum var. durum, is tetraploid with 28 chromosomes, and is the primary wheat for making pasta.Source: Wikipedia
What is tetraploid?
An organism is tetraploid if each autosomal cell contains 4 copies of each chromosome.
How might a mosaic tetraploid animal arise?
Mt a mother and father mosaic tetraploid animal having a special hug.
Is maize tetraploid or hexaploid?
hexaploid
Is Gossypium hirsutum tetraploid?
Yes
Why are tetraploid organisms fertile?
Most tetraploid organisms are fertile because they have four chromosomes. Triploids on the other hand have three chromosomes which make it infertile.
How many chromosomes would a tetraploid potato gametic cell contain?
The gamete would contain half the number of chromosomes as the tetraploid parent cell.
How many chromosomes will a hybrid have by crossing two somatic cells?
If both parents were diploid, then it would be tetraploid (4X).
What has the author Christina Helen Scarrott written?
Christina Helen Scarrott has written: 'Self-incompatibility in diploid and tetraploid lolium species'
Body cells contain 2 sets of chromosomes what are they called?
Polyploidy Polyploidy is having any number of extra sets of chromosomes. For a diploid organism, having two diploid sets would make it a tetraploid. For a haploid, having two haploid sets would make it diploid. For a tetraploid, having two tetraploid sets would make it octaploid.
Hexaploid wheat was produced synthetically by He and coworkers They mated the diploid species Aegilops tauschii and the tetraploid species T turgidum what is an accurate statem?
Aegilops tauschii contributed two chromosomes, and T. turgidum contributed four chromosomes.Diploid = 2n. Tetraploid = 4n. Hexaploid = 6n.Therefore, following meiosis you get 1n + 2n = 3n.3n gamete ---> 6n somatic cell.
How do you breed tetraploid plants?
One method involves soaking the buds or seeds in a chemical called colchicine, this induces genetic mutations in the DNA of the cells.
