NEET BIOLOGY

Detailed explanation-1: -The term “F1” means the “first filial generation, ” or the initial cross between two genetically distinct plants. Often an F1 cross does not yield the desired goals because some traits do not show up in those first generation seedlings.

Detailed explanation-2: -Mendel began his experiments by first crossing two homozygous parental organisms that differed with respect to two traits. An organism that is homozygous for a specific trait carries two identical alleles at a particular genetic locus. Organisms in this initial cross are called the parental, or P generation.

Detailed explanation-3: -P generation: Definition. A simple P generation definition is the parental generation. The p generation is the original pair of parents at the start of a genetic cross experiment. The first generation that is produced by the p generation is called the F1 generation.

Detailed explanation-4: -The cross between the true-breeding P plants produces F1 heterozygotes that can be self-fertilized. The self-cross of the F1 generation can be analyzed with a Punnett square to predict the genotypes of the F2 generation.

Detailed explanation-5: -The F1 generation or the first filial generation is the first generation of offspring produced from the cross of two organisms. The organisms subjected to the cross are known as the parental generation or the P generation of organisms.
