- Euploidy is the state of a cell or organism having the same number of each homologous chromosome, possibly excluding the sex-determining chromosomes. For example, most human cells have 2 of each of the 23 homologous monoploid chromosomes, for a total of 46 chromosomes.

Monogamy It is important to have a clear understanding of the nomenclature of monogamy because scientists use the term monogamy for different relationships. 1  Biologists, biological anthropologists, and behavioral ecologists often use the term monogamy in the sense of sexual, if not genetic, monogamy. Modern biological researchers, using the theory of evolution, approach human monogamy as the same in human and non-human animal species.

Monogamy Social monogamy refers to a male and female's social living arrangement (e.g., shared use of a territory, behaviour indicative of a social pair, and/or proximity between a male and female) without inferring any sexual interactions or reproductive patterns.In humans, social monogamy equals monogamous marriage. Social monogamy refers to two partners living together, having sex with each other, and cooperating in acquiring basic resources such as shelter, food, and money.

Biology This is an example of anisogamy or heterogamy, the condition in which females and males produce gametes of different sizes (this is the case in humans; the human ovum has approximately 100,000 times the volume of a single human sperm cell[2][3]).

Biology Dictionary â G Online Biology Dictionary (GAMET-) gametes /GAM-eets/ n. Haploid reproductive cells. Two gametes, one of each sex, fuse during fertilization to produce a zygote during sexual reproduction. A female reproductive cell is an ovum (or egg) and a male reproductive cell is a spermatozoon.

Homology (biology) In the context of biology, homology is the existence of shared ancestry between a pair of structures, or genes, in different species. A common example of homologous structures in evolutionary biology are the wings of bats and the arms of primates.

Karyotype Ploidy is the number of complete sets of chromosomes in a cell. 1  Polyploidy, where there are more than two sets of homologous chromosomes in the cells, occurs mainly in plants. 2  Haplo-diploidy, where one sex is diploid, and the other haploid.

- Monogamy is something most people say they believe in and want for themselves. Every survey ever done on this question shows a high percentage of people think monogamy is important to marriage and that affairs are wrong. And most people, when they marry, intend to be monogamous. But a belief in monogamy as an ideal doesn't prevent large numbers of people from having extramarital affairs.

- Ploidy is a term from genetics and cell biology. 1  It is used to indicate the number of chromosome sets in a cell. Most eukaryotes have either one set (called haploid) or two sets (called diploid). Some other organisms are polyploid, they have more than two sets of chromosomes. Some amphibians are triploid, with 3 sets.

Polyploidy Polyploidy, 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. 1  Polyploidy is common among plants and has been, in fact, a major source of speciation in the angiosperms. 2  Polyploid animals are far less common, and the process appears to have had little effect on animal speciation.

Gonochorism In biology, gonochorism (Greek offspring + disperse) or unisexualism or gonochory describes the state of having just one of at least two distinct sexes in any one individual organism. The term is most often used with animals, in which the individual organisms are often gonochorous. Gonochory is less common in plants.

Gamete Gametes of animals, some algae and fungi, and all higher plants exhibit an advanced form of heterogamy called oogamy. In oogamy one of the gametes is small and motile (the sperm), and the other is large and nonmotile (the egg).

Isogamy In several lineages (plants, animals), this form of reproduction independently evolved to anisogamous species with gametes of male and female types to oogamous species in which the female gamete is very much larger than the male and has no ability to move.

- Like monogamy, the term polygamy is often used in a de facto sense, applied regardless of whether the relationship is recognized by the state.[n 1] In sociobiology and zoology, researchers use polygamy in a broad sense to mean any form of multiple mating.
