F2 generation (second filial generation)
In a typical Mendel experiment, Mendel took two purebreeding lines (the parental generation) and crossed them to produce the 1st filial generation and sometimes would self cross these to produce the 2nd filial generation.
The parental generation is called the P generation. The offspring, or filial generation, is called F, with the first generation designated F1, the second F2,etc.
In Mendel's first experiment with pea plants, he crossed true-breeding plants with contrasting traits (e.g., tall and short). He found that the first generation (F1) offspring all displayed one of the traits, while the second generation (F2) showed a 3:1 ratio of the dominant to recessive trait. This led him to formulate his principles of inheritance, now known as Mendelian genetics.
TRUE!
They appeared in first and second generation offspring I think.
The second Mendelian Law is the Law of Segregation. It states that in a cross the parental traits do not merge in the first offspring generation (ie. the recessive, "weaker" trait does not disappear for good) but instead appear unchanged in the second offspring generation. For example, if you cross homozygous dwarf pea plants to homozygous tall, all members of the first offspring generation will be tall. This makes it seem as if the dwarf trait disappears, but it does not. If you inbreed the first offspring generation, you get 25% dwarf plants in the second offspring generation. So the "lost" trait reappears.
Three times as many shorts plants as tall plants.
P1 stands for "parental generation." This refers to the parents (mom and dad) who start off the pedigree. The P1 generation can then produce offspring (called the F1, or "first filial generation"). The F1 generation could then produce the F2 generation (or "second filial generation").
F2 generation (second filial generation)
no. in the second generation it will have a short offspring , but in the first generation it will have tall offspring
That should be "Mendel". The first generation means the children; the second generation means the grandchildren.
the probability of the offspring for a second generation.
