He discovered that genes came in pairs, he also found that they are inherited by distinct units. Mendel tracked the segregation of parental genes and their appearance in the offspring, as dominant or recessive traits]]> 2019-01-16 19:01:37 UTC https://padlet.com/emmie_alexander/ta6gw0y9997p/wish/321401408 emmie_alexander https://padlet.com/emmie_alexander/ta6gw0y9997p/wish/322515403  Mendel discovered that certain traits show up in offspring without any blending of parent characteristics.  For instance, the pea flowers are either purple or white--intermediate colors do not appear in the offspring cross-pollinated pea plants.  Mendel observed seven traits that are easily recognized and apparently only occur in one of two forms.]]> 2019-01-20 19:21:36 UTC https://padlet.com/emmie_alexander/ta6gw0y9997p/wish/322515403 emmie_alexander https://padlet.com/emmie_alexander/ta6gw0y9997p/wish/323749150 When Mendel’s results were rediscovered in 1900, his principles were tested in a wide spectrum of eukaryotic organisms (organisms with cells that contain nuclei). The results of these tests showed that Mendelian principles were generally applicable. Mendelian ratios (such as 3:1, 1:1, 9:3:3:1, and 1:1:1:1) were extensively reported, suggesting that equal segregation and independent assortment are fundamental hereditary processes found throughout nature. Mendel’s laws are not merely laws about peas, but laws about the genetics of eukaryotic organisms in general. The experimental approach used by Mendel can be extensively applied in plants. However, in some plants and in most animals, the technique of selfing is impossible. This problem can be circumvented by crossing identical genotypes. For example, an F₁ animal resulting from the mating of parents from differing pure lines can be mated to its F₁siblings (brothers or sisters) to produce an F₂ . The F₁ individuals are identical for the genes is question, so the F₁ cross is equivalent to a selfing.]]> 2019-01-24 02:05:18 UTC https://padlet.com/emmie_alexander/ta6gw0y9997p/wish/323749150 emmie_alexander https://padlet.com/emmie_alexander/ta6gw0y9997p/wish/323750158 Genetics- the study of heredity and the variation of inherited characteristics 
Traits- a distinguishing quality or characteristic, typically one belonging to a person
Hybrids- the offspring of two plants or animals of different species or varieties, such as a mule 
Genes- a unit of heredity which is transferred from a parent to offspring and is held to determine some characteristic of the offspring
Alleles- one of two or more alternative forms of a gene that arise by mutation and are found at the same place on a chromosome]]> 2019-01-24 02:12:27 UTC https://padlet.com/emmie_alexander/ta6gw0y9997p/wish/323750158 emmie_alexander https://padlet.com/emmie_alexander/ta6gw0y9997p/wish/323751898 The Law of Segregation: Each inherited trait is defined by a gene pair. Parental genes are randomly separated to the sex cells so that sex cells contain only one gene of the pair. Offspring therefore inherit one genetic allele from each parent when sex cells unite in fertilization.
The Law of Independent Assortment: Genes for different traits are sorted separately from one another so that the inheritance of one trait is not dependent on the inheritance of another.
The Law of Dominance: An organism with alternate forms of a gene will express the form that is dominant.]]> 2019-01-24 02:24:39 UTC https://padlet.com/emmie_alexander/ta6gw0y9997p/wish/323751898
