An image of multiple chromosomes, taken from many cells. Plant genetics is the study of genes, genetic variation, and heredity specifically in plants. [1] [2] It is generally considered a field of biology and botany, but intersects frequently with many other life sciences and is strongly linked with the study of information systems.
The first use of plant genetic resources dates to more than 10,000 years ago, when farmers selected from the genetic variation they found in wild plants to develop their crops. As human populations moved to different climates and ecosystems, taking the crops with them, the crops adapted to the new environments, developing, for example, genetic ...
Advanced Placement (AP) Human Geography (also known as AP Human Geo, AP Geography, APHG, AP HuGe, APHug, AP Human, HuGS, AP HuGo, or HGAP) is an Advanced Placement social studies course in human geography for high school, usually freshmen students in the US, culminating in an exam administered by the College Board.

The following outline is provided as an overview of and topical guide to genetics: . Genetics – science of genes, heredity, and variation in living organisms. [1] [2] Genetics deals with the molecular structure and function of genes, and gene behavior in context of a cell or organism (e.g. dominance and epigenetics), patterns of inheritance from parent to offspring, and gene distribution ...
A plant derived from the asexual vegetative reproduction of a parent plant, with both plants having identical genetic compositions. coalescent Having plant parts fused or grown together to form a single unit. cochleariform Concave and spoon-shaped. cochleate Coiled like a snail's shell. coenobium An arranged colony of algae that acts like a ...
Genetic resources are genetic material of actual or potential value, where genetic material means any material of plant, animal, microbial or other origin containing functional units of heredity. [1] Genetic resources is one of the three levels of biodiversity defined by the Convention on Biological Diversity in Rio, 1992.
The insecticide kills insects that eat the plants but is harmless to people. [20] In these plants, the new genes are put into the plant before it is grown, so the genes are in every part of the plant, including its seeds. [21] The plant's offspring inherit the new genes, which has led to concern about the spread of new traits into wild plants. [22]
Germplasm, genetic resources that are preserved for various purposes such as breeding, preservation, and research; International Treaty on Plant Genetic Resources for Food and Agriculture, an international agreement to promote sustainable use of the world's plant genetic resources; Genetic resources contribute to the provisioning ecosystem ...
