Mendel called the first two individuals that mate in a genetic cross the P generation.
The P generation
the P (parental) Generation
Mendel's first set of experiment is to study pea plants!
Mendel's Law of Dominance - The first law of Mendel states that "In a cross of parents that are pure for contrasting traits, only one form of the trait will appear in the progency" Mendel's Law of Dominance-When two pure breeding organisms of contrasting characters are crossed,only one character of the pair appears in the F1 generation.this is known as the dominant character(example:tallness).the other unexpressed or hidden character is known as the recessive character(example:dwarfness).
Gregor Mendel, a priest from a monastery in Central Europe. He entered the University of Vienna in 1851. He also taught at a nearby high school. While studying pea plants, he developed the punnet square, accurately predicting what traits the offspring will acquire from the parents, generation to generation. Gregor Mendel was considered as the father of genetics because he was the first one to understand how genetic inheritance worked.However he had no mechanism for genetic inheritance as neither chromosomes nor DNA had been discovered. All he had was a predictable reproducible phenomenon. It took the work of others to discover these mechanisms that produce the phenomenon Gregor Mendel studied.
He took two pea plants, one from a set he knew were always tall and one from a set he knew were always short. He cut off the male reproductive organs off one of the pea plants and so he knew that the pea plant would for sure not self pollenate. He then took the pollen off the other plant and pollenated the first plant. after the plant created new seed, mendel planted them and Let them grow the fist generation of offspring were all tall. he then let the 1st set of offspring self pollenate and and the results were 3 tall and 1 short. from this he created mendels laws.

Ronald Fischer was one of the first to apply Mendel's rules of genetic inheritance to Darwin and Wallace's rules of evolution by natural selection. This "new synthesis" occurred in the 1920s and 30s.

Mendel used pea pod plants for his early experiments. See http://www.mnsu.edu/emuseum/information/biography/klmno/mendel_gregor.html
1.) he was the first modren genetic engineer 2.) he was a monk and the church did'nt like his expeiriments 3.) he grew peas 4.)mendel studied bekeeping as a child 5.)mendels parents were both farmers 6.)back then mendel had a poor education
Mendel's Law - The first law of Mendel states that "In a cross of parents that are pure for contrasting traits, only one form of the trait will appear in the next generation. Offspring that are hybrid for a trait will have only the dominant trait in the phenotype."
Tt and TT were the genotypes of the true breeding plants that Mendel used in his two factor cross.
Genetic linkage was first discovered by the British geneticists William Bateson and Reginald Punnett shortly after Mendel's laws were rediscovered. The understanding of genetic linkage was expanded by the work of Thomas Hunt Morgan. Morgan's observation that the amount of crossing over between linked genes differs led to the idea that crossover frequency might indicate the distance separating genes on the chromosome. Alfred Sturtevant, a student of Morgan's, first developed genetic maps, also known as linkage maps.
