A new generation offspring is called what

The term used to describe the offspring of a new generation is:

1. F1 (First Filial) - This term is commonly used in genetics and breeding to describe the first generation of offspring produced by crossing two purebred parents.
2. F2 (Second Filial) - This term is used to describe the second generation of offspring produced by crossing two F1 individuals.
3. F3 (Third Filial) - This term is used to describe the third generation of offspring produced by crossing two F2 individuals, and so on.
4. F4 (Fourth Filial) - This term is used to describe the fourth generation of offspring produced by crossing two F3 individuals, and so on.

In general, the term "F1" is often used to refer to the first generation of offspring produced by crossing two purebred parents, while the terms "F2", "F3", etc. are used to refer to subsequent generations.

For example, if you cross a purebred Labrador Retriever with a purebred Golden Retriever, the offspring would be referred to as F1 Labradors. If you then cross two F1 Labradors, the offspring would be referred to as F2 Labradors, and so on.
