Three-point cross. In genetics, a three-point cross is used to determine the loci of three genes in an organism's genome. An individual heterozygous for three mutations is crossed with a homozygous recessive individual, and the phenotypes of the progeny are scored. The two most common phenotypes that result are the parental gametes; the two ...
Dihybrid cross. Dihybrid cross is a cross between two individuals with two observed traits that are controlled by two distinct genes. The idea of a dihybrid cross came from Gregor Mendel when he observed pea plants that were either yellow or green and either round or wrinkled. Crossing of two heterozygous individuals will result in predictable ...
The Punnett square is a square diagram that is used to predict the genotypes of a particular cross or breeding experiment. It is named after Reginald C. Punnett, who devised the approach in 1905. [3][4][5][6][7][8] The diagram is used by biologists to determine the probability of an offspring having a particular genotype.
One approach to cross ratio interprets it as a homography that takes three designated points to 0, 1, and ∞. Under restrictions having to do with inverses, it is possible to generate such a mapping with ring operations in the projective line over a ring. The cross ratio of four points is the evaluation of this homography at the fourth point.
Reciprocal cross. In genetics, a reciprocal cross is a breeding experiment designed to test the role of parental sex on a given inheritance pattern. [1] All parent organisms must be true breeding to properly carry out such an experiment. In one cross, a male expressing the trait of interest will be crossed with a female not expressing the trait.
To Mum's horror, Jim constructs and plants a cross, which is several feet tall, in Wilson's grave. Adam is awaiting an important phone call from work in regard to an American client. Jonny repeatedly rings Adam's phone, making him think the call is from work – until Adam smashes Jonny's phone with a hammer.
Software of unknown pedigree. SOUP stands for software of unknown (or uncertain) pedigree (or provenance), and is a term often used in the context of safety-critical and safety-involved systems such as medical software. SOUP is software that has not been developed with a known software development process or methodology, or which has unknown or ...
