Ocular dominance, sometimes called eye preference or eyedness, [ 1] is the tendency to prefer visual input from one eye to the other. [ 2] It is somewhat analogous to the laterality of right- or left- handedness; however, the side of the dominant eye and the dominant hand do not always match. [ 3] This is because both hemispheres control both ...
The Punnett square is a visual representation of Mendelian inheritance, a fundamental concept in genetics which is discovery of Gregor Mendel. [ 10] For multiple traits, using the "forked-line method" is typically much easier than the Punnett square. Phenotypes may be predicted with at least better-than-chance accuracy using a Punnett square ...
An epicanthic fold or epicanthus[ 6] is a skin fold of the upper eyelid that covers the inner corner (medial canthus) of the eye. [ 3] However, variation occurs in the nature of this feature and the possession of "partial epicanthic folds" or "slight epicanthic folds" is noted in the relevant literature. [ 7][ 8][ 9] Various factors influence ...
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.
Pedigree of horse Shagya IX b. 1895. In the practice of selective breeding of animals, particularly in animal fancy and livestock, including horses, pedigree charts are used to track the ancestry of animals and assist in the planning of suitable breeding programs to enhance desirable traits. Breed registries are formed and are dedicated to the ...
Most forms of EDS are inherited in an autosomal dominant pattern, which means only one of the two copies of the gene in question must be altered to cause a disorder. A few are inherited in an autosomal recessive pattern, which means both copies of the gene must be altered for a person to be affected.
By performing a test cross, one can determine whether the individual is heterozygous or homozygous dominant. [ 1] In a test cross, the individual in question is bred with another individual that is homozygous for the recessive trait and the offspring of the test cross are examined. [ 2] Since the homozygous recessive individual can only pass on ...
In genetics, the phenotype (from Ancient Greek φαίνω (phaínō) 'to appear, show' and τύπος (túpos) 'mark, type') is the set of observable characteristics or traits of an organism. [ 1][ 2] The term covers the organism's morphology (physical form and structure), its developmental processes, its biochemical and physiological ...
