Answer 1

The symbol ‘F’ in the results of a test cross stands for filial.

Explanation:

The letter ‘F’ is used to denote filial generations in genetics, which are the generations of offspring following a parental (P) generation. For example, the first generation of offspring is called the F₁ (first filial) generation. This notation helps in tracking the inheritance of traits from one generation to the next in genetic crosses such as test crosses.
