Question

Define the following term filial generation.

Answer 1

The filial generation is a term used to represent the sets of offsprings produced by controlled reproduction. It can be either produced by self-fertilization or cross-fertilization.

Complete answer:
Gregor Mendel, conducted hybridization experiments on garden peas for seven years and proposed the laws of inheritance in the living organisms.
The filial generation is a successive generation that results from the genetic controlled cross made between two parents. It is represented by the alphabet “F”. The generation of parents is represented by the symbol “P”, parental generation. The filial generations can be ${F_1}$, ${F_2}$, and so on.
The ${F_1}$ represents the first filial generation that is produced by the cross made between the two parents. The ${F_1}$ generation used to do reproduction and produce second filial generation or ${F_2}$ generation.
These terms can be explained by the following example:
When Mendel studied the inheritance pattern in pea plants, he produced pure lines by using self-fertilization in the pea plant. He crossed a homozygous tall (TT) plant with a homozygous dwarf (tt) plant, he obtained a heterozygous tall (Tt) plant as a ${F_1}$ generation. Then he self-crossed the ${F_1}$ generation to obtain parental traits in ${F_2}$ generation. On crossing, he obtained three heterozygous tall (Tt) plants and one homozygous dwarf (tt) plant as the offspring of ${F_2}$ generation.

Note: The inheritance is the transfer of traits from one generation to the other generation. A trait is a specific character that is inheritable in nature. The homozygous is a condition that contains the same alleles of a particular gene while heterozygous is the condition that contains two different alleles of a gene.
