Karyogamy Haploid organisms such as fungi, yeast, and algae can have complex cell cycles, in which the choice between sexual or asexual reproduction is fluid, and often influenced by the environment. Some organisms, in addition to their usual haploid state, can also exist as diploid for a short time, allowing genetic recombination to occur.

MADMAN BIOLOGY A phylogeny is the evolutionary history of a species or group of species. They separate organisms by evolutionary relationships (clades), based on comparative cytology and the comparison of DNA, morphological characters, and shared ancestral and derived characters.

What are 'haploid' or 'diploid' cells? Definition. Since ploidy refers to the number of sets of chromosomes in a biological cell, a cell containing two sets of chromosomes comes to be known as a diploid cell. Humans have a total of 23 pairs of chromosomes, which brings it to a total of 46.

Aneuploidy Aneuploidy is the presence of an abnormal number of chromosomes in a cell, such as having 45 or 47 chromosomes when 46 is expected.It does not include a difference of one or more complete sets of chromosomes, which is called euploidy.An extra or missing chromosome is a common cause of genetic disorders, including some human birth defects. Some cancer cells also have abnormal numbers of chromosomes.Aneuploidy originates during cell division when the chromosomes do not separate properly between the two cells.t does not include a difference of one or more complete sets of chromosomes, which is called euploidy. An extra or missing chromosome is a common cause of genetic disorders, including some human birth defects. Some cancer cells also have abnormal numbers of chromosomes.

What is polyploidy? Polyploidy is the condition in which an organism has extra sets of chromosomes. It can be defined as a chromosomal alteration in which the organism posses more than two complete chromosome sets. Classified as an accident in cell division. Polyploidy is the condition in which an organism has extra sets of chromosomes.

- From Wikipedia, the free encyclopedia. Metaplasia (Greek : change in form) is the reversible replacement of one differentiated cell type with another mature differentiated cell type.The change from one type of cell to another may generally be a part of normal maturation process or caused by some sort of abnormal stimulus.etaplasia is not synonymous with dysplasia and is not directly considered carcinogenic. It is also contrasted with heteroplasia, which is the abnormal growth of cytologic and histologic elements without a stimulus.

- Aneuploidy. Aneuploidy-the abnormal condition were one or more chromosomes of a normal set of chromosomes are missing or present in more than their usual number of copies.

Population genetics Population genetics. Population genetics is a subfield of genetics that deals with genetic differences within and between populations, and is a part of evolutionary biology. Studies in this branch of biology examine such phenomena as adaptation, speciation, and population structure.

aneuploidy aneuploidy. the state of having chromosomes in a number that is not an exact multiple of the haploid number; seen in karyotypes which have a small number of extra chromosomes or have a small number less than normal.ommon forms of aneuploidy are trisomy in which there is one extra chromosome and monosomy in which there is one less, than the normal 46. They rarely cause specific eye diseases but affected individuals present ocular manifestations.

How Chromosome Mutations Occur A chromosome mutation that results in individuals with more than one haploid set of chromosomes in a cell is termed polyploidy. A haploid cell is a cell that contains one complete set of chromosomes. Our sex cells are considered haploid and contain 1 complete set of 23 chromosomes.

- In biology, a phylum (/ˈfaɪləm/; plural: phyla) is a taxonomic rank below kingdom and above class. Traditionally, in botany the term division was used instead of phylum, although from 1993 the International Code of Nomenclature for algae, fungi, and plants accepted the designation phylum.

- Cladistics, also known as parsimony analysis, is a technique widely applied in biology to classify organisms and identify evolutionary trends. However, in principle the method can be applied to any type of information where it suspected that there are underlying relationships and groupings.
