The F1 generation consists of the offspring of a
cross between two parents; the F2 generation consists of the offspring of a cross between two individuals in the same F1 generation.
they are just different

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.
Simple machines come to mind. Let us say a pulley is suspended on a secure structure. One end of the rope is tied to a heavy object. The rope makes a few round on the pulley. The other end of the rope comes out and can be held with relative ease to keep the heavy object afloat or lift it up. The human effort would be 'n' times less than the weight of the object, where 'n' is the number of times the rope winds around the pulley. A lever is another example. The beam is resting on a fulcrum. One downward force (F1) is acting L1 meters from the fulcrum. The balancing downward force (F2) will be L2 meters from the fulcrum on the other side. The principle of moments says that F1 * L1 = F2 * L2. With a rigid beam (the beam does not break with the forces). If L1 = 2 * L2, then F1 = 0.5 * F2.
B (F) = 32 + A (C) x 1.8 F1 = 32 + 75 x 1.8 = 32 + 135 = 167 Fahrenheit F2 = 32 + 80 x 1.8 = 32 + 144 = 176 Fahrenheit Answer = 167 - 176 F

f2 generation
F2 refers to the F2 generation in genetics. First you have the P1 generation, or the 1st parents to cross. Next, their offspring is called the F1 generation. When the F1 generation offspring cross, then the F2 generation appears.
F1 are the first set of offspring, and F2 are the F1's offspring.
F1 and F2
F1 Generation
f2 generation
it showed him a new different generation of offspring. :D
The beginning generation, the parents of F1 generation and the grandparents of F2 generation.
Crossing organisms from the F1 generation produces the F2 generation.
The offspring of the P1 generation are called the F1, or first children of an organism. The offspring of the F1 generation are then called the F2 generation of the original organism.
In the P generation, one parent is homozygous dominant and the other parent is homozygous recessive. In the F1 generation, the product of a cross between the P generation, the offspring are all heterozygous. In the F2 generation, the product of a cross between the F1 generation, the expected result is 1/4 homozygous dominant, 1/2 heterozygous, and 1/4 homozygous recessive.
