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 uses of test crosses were in Gregor Mendel’s experiments in plant hybridization.While studying the inheritance of dominant and recessive traits in pea plants, he explains that the “signification” (now termed zygosity) of an individual for a dominant trait is determined by the expression patterns of the following generation.
The idea of a dihybrid cross came from Gregor Mendel when he observed pea plants that were either yellow or green and either round or wrinkled. Crossing of two heterozygous individuals will result in predictable ratios for both genotype and phenotype in the offspring. The expected phenotypic ratio of crossing heterozygous parents would be 9:3:3 ...
Recent work shows this may not be of hybrid origin (Nazre, 2014) Gossypium hirsutum: Upland cotton: Malvaceae: hybrid origin: Confirmed: Uncertain, referred to as 'A' and 'D' Polyploid (formed <1MYA) 2n =4x=52: Wendel and Cronn 2003: Polyploidization likely led to agronomically significant traits (Applequist et al., 2001) Hibiscus sabdariffa ...
Modern genetic analysis began in the mid-1800s with research conducted by Gregor Mendel. Mendel, who is known as the "father of modern genetics", was inspired to study variation in plants. Between 1856 and 1863, Mendel cultivated and tested some 29,000 pea plants (i.e., Pisum sativum).
Genetically modified crops are plants used in agriculture, the DNA of which has been modified using genetic engineering techniques. In most cases, the aim is to introduce a new trait to the plant which does not occur naturally in the species. As of 2015, 26 plant species have been genetically modified and approved for commercial release in at ...

The Fabaceae (/ f ə ˈ b eɪ s i. iː,-ˌ aɪ /) or Leguminosae, [6] commonly known as the legume, pea, or bean family, are a large and agriculturally important family of flowering plants. It includes trees , shrubs , and perennial or annual herbaceous plants , which are easily recognized by their fruit ( legume ) and their compound, stipulate ...
