what is the difference between autopolyploidy and allopolyploidy?
2569
The main difference between autopolyploidy and allopolyploidy is that autopolyploidy is the containment of multiple sets of chromosomes that are derived from the same species whereas allopolyploidy is the containment of multiple sets of chromosomes that are derived from different species.

Finally, polyploidy in plants is a type of sympatric speciation in which two sympatric species having different chromosome numbers or morphologies form a hybrid, and that hybrid produces offspring with a doubled number of chromosomes (one full genome from each parental species).

The most observable difference is the way in which cytokinesis occurs. In plants, a new cell wall is formed between the new daughter cells, while in animal cells the cell membrane contracts to pinch the parent cell in the daughter cells.

Most plants are diploid. They have two identical sets of chromosomes in each cell. Polyploids are plants with more than two sets of chromosomes. A tetraploid is only one of a whole series of polyploids.

Answer: The primary functional difference between mitotic anaphase I and meiotic anaphase II is the type and amount of cells at the end result. anaphase I mitosis has two diploid cells. anaphase II meiosis has four haploid cells.

The main difference between animal cell mitosis and plant cell mitosis is that in animal cell undergoes cell furrowing while plant cell do not because of the rigid cell wall. The major difference is during the last phase of mitosis , that is telophase. And thus, cytokinesis occurs differently in both the cells.

What is the ploidy level of endosperm in angiosperms? Endosperm is triploid (3n) in most of the angiospermic plant as two polar nuclei fuse with a male gamete and three of them are haploid. But the number varies from 2n to 15n in different species.

Diploid is a cell or organism that has paired or two sets of chromosomes, one from each parent. Haploid or monoploid is a cell or organism that has just a single copy of each chromosome. These cells are formed after mitotic cell division.

Autotroph vs. Heterotroph. Autotrophs are organisms that can produce their own food from the substances available in their surroundings using light (photosynthesis) or chemical energy (chemosynthesis). Heterotrophs cannot synthesize their own food and rely on other organisms — both plants and animals — for nutrition.

For the most part, in mitosis, diploid cells are partitioned into two new diploid cells, while in meiosis, diploid cells are partitioned into four new haploid cells. ... The daughter cells produced by mitosis are identical, whereas the daughter cells produced by meiosis are different because crossing over has occurred.

Euploidy in Animals As a general rule polyploids can be tolerated in plants, but are rarely found in animals. One reason is that the sex balance is important in animals and variation from the diploid number results in sterility.

Endosperm is triploid (3n) in most of the angiospermic plant as two polar nuclei fuse with a male gamete and three of them are haploid. But the number varies from 2n to 15n in different species.

albicans is a diploid, polymorphic fungus, switching readily from yeast to hyphal (and pseudohyphal) growth and back. In contrast, C. glabrata is strictly haploid and normally grows only in the yeast form (Kaur et al., 2005).

Diploid refers to the number of complete chromosome sets present in each cell of an organism: diploid cells contain two complete sets. Haploid organisms, on the other hand, only contain one complete chromosome set.

The main difference between the two types of plant bodies involved in alternation of generations is that gametophytes produce gametes, and sporophytes produce spores. Essay: What is double fertilization? Double fertilization is the process in which one sperm fertilizes an egg and the other forms a triploid cell.

Which of the following statements describes a major difference between meiosis II and mitosis in a diploid animal? Meiosis II occurs in a haploid cell, while mitosis occurs in diploid cells. A triploid cell contains three sets of homologous chromosomes.

The pollen grain, itself is diploid. It is the male gametophyte, thee generation which produces the gametes. ... So, there ploidy level is n or we can say that they are haploid .
