A Whitefaced Blue (Turquoise) female. The science of rosy-faced lovebird colour genetics deals with the heredity of colour variation in the feathers of the species known as Agapornis roseicollis, commonly known as the rosy-faced lovebird or peach-faced lovebird. Rosy-faced lovebirds have the deepest range of mutations available of all the ...
Suntory "blue" rose Rosa 'Cardinal de Richelieu' rose, used for the first genetic engineering experiments. Scientists have yet to produce a truly blue-colored rose; however, after thirteen years of collaborative research by an Australian company, Florigene, and a Japanese company, Suntory, a rose containing the blue pigment delphinidin was created in 2002 by genetic engineering of a white rose ...
The list of organisms by chromosome count describes ploidy or numbers of chromosomes in the cells of various plants, animals, protists, and other living organisms. This number, along with the visual appearance of the chromosome, is known as the karyotype, [1][2][3] and can be found by looking at the chromosomes through a microscope.
These conditions are mediated by the OPN1SW gene on Chromosome 7 which encodes the S-opsin protein and follows autosomal dominant inheritance. [44] The cause of blue–yellow color blindness is not analogous to the cause of red–green color blindness, i.e. the peak sensitivity of the S-opsin does not shift to longer wavelengths.
Genetics is the study of genes, genetic variation, and heredity in organisms. [1][2][3] It is an important branch in biology because heredity is vital to organisms' evolution. Gregor Mendel, a Moravian Augustinian friar working in the 19th century in Brno, was the first to study genetics scientifically.

Genetics is the study of genes and tries to explain what they are and how they work. Genes are how living organisms inherit features or traits from their ancestors; for example, children usually look like their parents because they have inherited their parents' genes. Genetics tries to identify which traits are inherited and to explain how ...
Genetic linkage is the tendency of DNA sequences that are close together on a chromosome to be inherited together during the meiosis phase of sexual reproduction.Two genetic markers that are physically near to each other are unlikely to be separated onto different chromatids during chromosomal crossover, and are therefore said to be more linked than markers that are far apart.
