Vegetative reproduction (also known as vegetative propagation, vegetative multiplication or cloning) is a form of asexual reproduction occurring in plants in which a new plant grows from a fragment or cutting of the parent plant or specialized reproductive structures, which are sometimes called vegetative propagules.
A represents the dominant allele for color (yellow), while a represents the recessive allele (green). If each plant has the genotype RrAa, and since the alleles for shape and color genes are independent, then they can produce four types of gametes with all possible combinations: RA, Ra, rA, and ra.
Cross-pollination, where pollen from one plant can only fertilize a different plant; Asexual propagation (e.g. runners from strawberry plants) where the new plant is genetically identical to its parent; Apomixis (self-cloning), where seeds are produced asexually and the new plant is genetically identical to its parent
Gramene [17] is an online web database resource for plant comparative genomics and pathway analysis based on Ensembl technology. Plant Genome DataBase Japan [18] (PGDBj) is a website that contains information related to genomes of model and crop plants from databases. It has three main components: ortholog db, DNA marker and linkage map db, and ...
Plants have a number of different means to attract pollinators including color, scent, heat, nectar glands, edible pollen and flower shape. Along with modifications involving the above structures two other conditions play a very important role in the sexual reproduction of flowering plants, the first is the timing of flowering and the other is ...
