In the study of genetics, the offspring of the P generation is referred to as the (A) wild-type generation (B) F1 generation (C) genotype (D) F2 generation
Answer (1)
In the study of genetics, the offspring of the P generation is referred to as the F1 generation. Let's break it down step-by-step:
P Generation (Parental Generation): This is the initial set of parents in a genetic cross. They are usually purebred or homozygous for certain traits, which means they carry two identical alleles for those traits. For example, if studying pea plants, one plant might be homozygous for tallness (TT) and another for shortness (tt).
F1 Generation (First Filial Generation): This refers to the first generation of offspring obtained from the P generation cross. The offspring in the F1 generation are always hybrids, meaning they carry two different alleles for a given trait (e.g., Tt, where 'T' stands for tallness and 't' stands for shortness).
Answer Choice: Given the options, the correct answer is (B) F1 generation. The F1 generation are the immediate offspring of the P generation.
This foundational concept in genetics helps predict how traits are inherited through successive generations, building the groundwork for understanding dominant and recessive alleles.
