The independent segregation of pairs of homologous chromosomes in meiosis provides the biological basis for mendel's principles of heredity the principle of independent assortment indicates that the separation of alleles at one locus is independent of the separation of other pairs at other loci.
Genetics is the study of how heritable traits are transmitted from parents to offspring the theory of natural selection states that variations occur, but charles darwin couldn't explain how. While mendel's research was with plants, the basic underlying principles of heredity that he discovered also apply to people and other animals because the mechanisms of heredity are essentially the same for all complex life forms. Mendel instead believed that heredity is the result of discrete units of inheritance, and every single unit (or gene) was independent in its actions in an individual's genome according to this mendelian concept, inheritance of a trait depends on the passing-on of these units.
The manifestation or appearance of a characteristic from a given genotype the genotype determines the potential for development and the phenotype is alsodetermines by other genes and envirinmental effects. -this man discovered the basic principles of heredity by studying crosses between pea plants - he published his results in 1866, but their significance wasn't realized until 1900, which marked the launch of modern genetics. If the results of a genetic cross were tt, tt, tt, tt what would be the probalilty of getting a purebred tall note that t is dominant (tall) and t is recessive (short) a.

What three principles of heredity did mendel discover gregor mendel discovered three principles of heredity: that the inheritance of each trait or gene is determined by the units that are passed down via descendants unchanged, that an individual will get one unit from each of their parents for each trait and that a trait may not show up in one individual yet it can still be passed on to a descendant.

Two principles of heredity were formulated by gregor mendel in 1866, based on his observations of the characteristics of pea plants from one generation to the next the principles were somewhat modified by subsequent genetic research.
