The genetic bases of the seven pairs of contrasting traits in the garden pea that were described by the ‘father of genetics’, Gregor Mendel, have long puzzled scientists. The discovery of the genetic variants underlying these traits sheds light on the ‘inherited factors’ that Mendel proposed...
Common oat (Avena sativa) is an important cereal crop serving as a valuable source of forage and human food. Although reference genomes of many important crops have been generated, such work in oat has lagged behind, primarily owing to its large, repeat-
Molecular Genetics and Metabolism is a contribution to the understanding of the metabolic basis of disease. The journal publishes articles describing investigations that use the tools of biochemistry and molecular biology for studies of normal and diseased states. Research Areas include: •Inherited Meta...
A genetic situation where the phenotype of the heterozygote is a mixture of the dominant and the recessive traits. What happens to the alleles in incomplete dominance? Neither of the alleles wins; both contribute to the phenotype. How does the heterozygous phenotype compare to the homozygous phenot...
The inheritance of this meiotic restitution mechanism and two independent types of premature cytokinesis were described as independent monogenic recessively inherited traits (Mok and Peloquin 1975a, b). The subsequent re-investigation of those cytological mechanisms by Ramanna (1979) drew a more ...

4. Mendels Ideas and the Law of independent Assortment Mendels Second Set of Experiments • Mendel also performed dihybrid crosses 双因子杂合 试验, which enabled him to consider how two traits are inherited relative to one another. Dihybrid crosses: In contrast to a monohybrid cross, a ...
Understanding genetics with pea plants and the Punnett squareThis video uses a Punnett square to illustrate how Gregor Mendel determined the way traits are inherited. See all videos for this article In 1854 Abbot Cyril Napp permitted Mendel to plan a major experimental program in hybridization at ...
Mendel suspected that traits were inherited as discrete units, and, although he knew nothing of the physical or chemical nature of genes at the time, his units became the basis for the development of the present understanding of heredity. All present research in genetics can be traced back to...
