Inheritance, Mendelism, and Mutation

Mending Mendelism

Teaching .Mendelism

regor Mendel is rightly credited as being the "father of modern " He presented the results of his pea at a of his local natural history society in two lectures 1865. His paper was published in the proceedings of the society the next year. From his breeding experiments with the edible pea, he recog­ nized the phenomena of what we call dominance and recessiveness, segregation of assortment of dif...

A.N. Kolmogorov’s defence of Mendelism

In 1939 N.I. Ermolaeva published the results of an experiment which repeated parts of Mendel's classical experiments. On the basis of her experiment she concluded that Mendel's principle that self-pollination of hybrid plants gave rise to segregation proportions 3:1 was false. The great probability theorist A.N. Kolmogorov reviewed Ermolaeva's data using a test, now referred to as Kolmogorov's,...

Self Flower-Color Inheritance and Mutation in Mirabilis Jalapa L.

Mirabilis jalapa, commonly known as ((Four O’clock”’ “Sweet Marvel of Peru,” or ‘(Printoponite,” belongs to the Nyctaginaceae. This species is cultivated for the brilliant color and pleasing odor of its flowers. Due to its simplicity, the breeding behavior of the self flower colors has furnished classical material for illustrating the simple laws of inheritance. It may be shown, however, that t...

Mutation load under vegetative reproduction and cytoplasmic inheritance.

For reasons that remain unclear, even multicellular organisms usually originate from a single cell. Here I consider the balance between deleterious mutations and selection against them in a population with obligate vegetative reproduction, when every offspring is initiated by more than one cell of a parent. The mutation load depends on the genomic deleterious mutation rate U, strictness of sele...
