Difference in dihaploids and double haploids?
Haploid genomes contain a single copy of each chromosome while diploid genomes have two homologous copies. Usually organisms with a diploid genome inherit one chromosome of the pair from each parent. Double haploid occurs by doubling of the haploid genome resulting in pairs of chromosomes that are identical, so homozygous at each locus. This can be created artifically by using colchicine, which prevents microtubule polymerisation and therefore chromosome separation at meiosis where the chromosome number would be halved. This procedure is useful during plant breeding because of the homozygous plants produced.
How does the number of chromosomes in a diploid compare to the number of chromosomes in a haploid?
The diploid number is "2n" and the haploid number is "n". Humans have 46 chromosomes, which are equal to the diploid number. half of these chromosomes are the haploid number, which is = 23.
What cell begins meiosis and mitosis?
The process of meiosis always begins with diploid cells. The chromosomes in the cells divide, so the result is four haploid cells.
Does a German shepherd have both haploid and diploid cycles?
Of course they do. All dogs do. All mammals do. All things with cells have periods when their chromosomes are haploid and diploid during cell division.
Is the definitive nucleus in plants haploid in number?
No. Haploid is a term used to describe the genetic makeup of an animal with only one set of sister chromosomes. Humans are diploid organisms, which means they have 46 chromosomes, two sets of 23 (one from mother, on from father). Plants (and fungi) however, have a different developmental pathway which in certain organisms can result in only one set of chromosomes, or haploid. The huge diversity of plants include haploid, diploid, and polyploid (many copies of each chromosome) species.
What kind of Cell results when a diploid and a haploid gamete fuse during fertilization?
I am not sure what your saying, but i think you mean "what are the haploid cells involved in fertilization?" In this case the answer would be " sperm and egg cells", which then makes a diploid.

Is the cell in prophase II an haploid cell?
Monkeys have both diploid and haploid cells. Organisms produce these 2 general cell types. There are several differences between diploid and haploid cells. Diploid means it contains 2 complete sets of chromosome (2n). Haploid means the cell contains 1 st of chromosomes (n). Diploid cells are the result of mitosis while haploid cells is the product of meiosis. Every species has a different number of chromosomes.
Are cells diploid or haploid at the end of cell division?
They are haploid. As meosis produces sex cells (sperm and eggs) they must have half the genetic material, so when fertilisation occurs the gamete formed has one full set of chromosomes, it is diploid.
Is the egg in human egg cells haploid or diploid?
Officially, the egg cell is the ovum which is haploid. However, the precursor cells in the ovaries, which people commonly refer to as eggs, are diploid. During the process known as oogenesis, the diploid cells undergo meiosis and become haploid.
What cell begins meiosis and mitosis?
The process of meiosis always begins with diploid cells. The chromosomes in the cells divide, so the result is four haploid cells.
Is the end product of mitosis haploid or diploid?
Mitosis produces DIPLOID cells- remember in mitosis your INCREASING the number of CELLS but the chromosome number is the SAME as the parentso a parent that has a (DIPLOID number of 10)will produce at the end of mitosis will produce 2 children with a diploid number of (10)That is why Mitosis is CONSERVATIVE.So in actuality, 1 diploid cell will produce 2 diploid cells in mitosisThe above is only true if the starting cell is itself diploid. However there are plenty of instances, especially in plants, in which cells that are haploid (the ones that give rise to pollen and egg, and endosperm nuclei, for example) or multiploid (hexaploid wheat, for example) undergo mitosis, and the cells that are produced have the same ploidy as the starting cell. Always. As noted above, mitosis is conservative. However, you ought not assume that you started with a diploid cell.
Summarize the difference between a haploid cell and a diploid cell?
A haploid cell contains half the total number of chromosomes. it is used during sexual reproduction to produce diploid cells.
Does a German shepherd have both haploid and diploid cycles?
Of course they do. All dogs do. All mammals do. All things with cells have periods when their chromosomes are haploid and diploid during cell division.
Why are egg and sperm cells haploid?
are little more than flagellated nuclei. Each consists of a head, which has an acrosome at its tip and contains a haploid set of chromosomes in a compact, inactive, state.
