F1 cross is the crossing that takes place at the first filial generation before the second filial generation.In this crossing,two homozygous parents are crossed together to get one homozygous offspring and three heterozygous offspring which will give a phenotypic ratio of 3:1. First filial generation is also the phase where the production/crossing started.I hope i av been able to answer your question to my own knowledge as a baby microbiologist

What is p and F1?
P represents the parental generation in a genetic cross. F1 represents the offspring of the P generation.
What is the phenotype in the F1 generation that disappears in a one trait test cross?
The recessive trait phenotype disappears in a one-trait test cross in the F1 generation. This phenotype can reappear in the F2 generation.
Is M1 and F1 generations same in the mendelian cross?
No, the M1 generation refers to the parent generation, or original purebred parental lines, in a Mendelian cross. The F1 generation, on the other hand, refers to the first-generation offspring resulting from the cross between the parental lines.
How many gametes are formed in f1 generation of trihybrid cross?
In a trihybrid cross, which involves three traits, each parent forms 8 different gametes due to independent assortment of alleles during meiosis. Therefore, in the F1 generation of a trihybrid cross, 64 different genotypic combinations are possible (8 x 8).
Hybrid organisms prodused from a cross between two pure-breeding organisms belong to which generation is F1?
The hybrid organisms produced from a cross between two pure-breeding organisms belong to the F1 generation, which stands for the first filial generation. These offspring are the first generation of offspring resulting from the cross of two parent organisms with different genetic backgrounds.
