Also called functionalism. The Darwinian view that many or most physiological and behavioral traits of organisms are adaptations that have evolved for specific functions or for specific reasons (as opposed to being byproducts of the evolution of other traits, consequences of biological constraints, or the result of random variation). adaptive radiation The simultaneous or near-simultaneous ...
Overo is a Spanish word, originally meaning "like an egg". [1] The most common usage refers to frame overo , but splashed white and sabino are also considered "overo". [ 2 ] [ 3 ] A horse with both tobiano and overo patterns is called tovero .
In biology, phylogenetics (/ ˌ f aɪ l oʊ dʒ ə ˈ n ɛ t ɪ k s,-l ə-/) [1] [2] [3] is the study of the evolutionary history of life using genetics, which is known as phylogenetic inference. It establishes the relationship between organisms with the empirical data and observed heritable traits of DNA sequences, protein amino acid sequences ...
The quiz randomly chooses terms from the Talking Glossary and asks the user to select a term name to match the definition shown. Hints are available for each question, and at the end of the quiz all users are able to print a "Certificate of Completion" that includes the date the test was taken, number of correct answers, and the user's name.
A knockout mouse (left) that is a model for obesity, compared with a normal mouse. There are several thousand different strains of knockout mice. [3] Many mouse models are named after the gene that has been inactivated.
A metaphase cell positive for the BCR/ABL rearrangement using FISH. Cytogenetics is essentially a branch of genetics, but is also a part of cell biology/cytology (a subdivision of human anatomy), that is concerned with how the chromosomes relate to cell behaviour, particularly to their behaviour during mitosis and meiosis. [1]
In genetics, a locus (pl.: loci) is a specific, fixed position on a chromosome where a particular gene or genetic marker is located. [1] Each chromosome carries many genes, with each gene occupying a different position or locus; in humans, the total number of protein-coding genes in a complete haploid set of 23 chromosomes is estimated at ...
The petals can be purple or white depending on the alleles present in the pea plant. [4] However, other traits are only partially influenced by genotype. These traits are often called complex traits because they are influenced by additional factors, such as environmental and epigenetic factors. Not all individuals with the same genotype look or ...
