As a result, DeKalb was the leader in U.S. hybrid seed corn sales from the mid-1930s until the mid-1970s (Crabb 1948. Roberts 1999). [2] In 1982 DeKalb formed a joint venture with Pfizer, called DeKalb-Pfizer Genetics, and in 1985 the name was changed to DeKalb Corporation. The seed business was spun off as DeKalb Genetics Corporation in 1988. [4]
Female rats wiggle their ears when they are in heat, to excite male rats and encourage them to mate. [4] Ear wiggling was a shtick in Hal Roach comedies such as Laurel and Hardy and Our Gang. To achieve this effect, performers such as Stan Laurel would have their ears pulled by threads which would not be visible in the film. [5]
Microtia is a congenital deformity where the auricle (external ear) is underdeveloped. A completely undeveloped auricle is referred to as anotia.Because microtia and anotia have the same origin, it can be referred to as microtia-anotia. [1]
The common term, earwig, is derived from the Old English Δ“are, which means ' ear ', and wicga, which means ' insect ', or literally, ' beetle '. [2] Entomologists suggest that the origin of the name is a reference to the appearance of the hindwings, which are unique and distinctive among insects, and resemble a human ear when unfolded.
Stratified mass selection for ear size over 22 cycles [clarification needed] has drastically altered plant phenotype in the maize population Zacatecas 58. Plants in the C22 cycle were 50 cm taller had twice the leaf area index, reached anthesis 7 days later and had a 30% higher harvest index than C0 (Table 1) [ clarification needed ...
Variety-specific genetic use restriction technologies destroy seed development and plant fertility by means of a "genetic process triggered by a chemical inducer that will allow the plant to grow and to form seeds, but will cause the embryo of each of those seeds to produce a cell toxin that will prevent its germination if replanted, thus ...

Consider the gene pool of a seed orchard crop or other source of seeds with parents. The gene pool is large as there are many seeds in a seed crop, so there is no genetic drift. The probability that the first gene originates from genotype i in the seed orchard is p i, and the probability that the second originates from genotype j is p j.
