The Color Genes of Speciation in Plants. The red flowers of M. cardinalis have petals rich in carotenoids (yellow pigment) and anthocyanins (pink pigment) and are full of nectar. In contrast, the pink flowers of M. lewisii, in addition to little nectar,

The main objectives of this thesis are to study patterns and processes of plant speciation in arctic and alpine diploid plants. Cryptic species are here referred to as morphologically similar individuals belonging to the same taxonomic species but that ar

Enrolling in Biology 121 Students majoring in biology at Randolph-Macon College receive an education that is broadly based in the liberal arts and embraces both scientific and humanistic studies. Students thus view their area of specialization - biology -

Nov 19, 2019 · These new gametes will be incompatible with the normal gametes produced by this plant species. However, they could either self-pollinate or reproduce with other autopolyploid plants with gametes having the same diploid number. In this way,

RMC plant, unlike normal concrete (manufacture on site), will require a large facility. It will include assembly of tools, cement batches, conveyors, and aggregate bins, cement bins etc. Half the production is carried out within the plant and the second h

Plant speciation, the book. One day in 1968 I sat down and drew up an outline of a thesis that I thought should be developed in book form. The thesis was the reticulate mode of plant evolution. Plant evolution proceeds in cycles: divergence to the species

People argued that the evidences of sympatric speciation are in fact examples of micro-geographic speciation. In general, this is not now the preferred explanation. Rather, it is the result of hybridisation between closely related species, followed by nat
