Question

Varieties of plants in which self-fertilization produces offspring that are identical to the parents are referred to as

Answer 1

Pure-breeding

Step-by-step explanation:

A pure-breeding plant is the one that is true to its type. This means that the plant is homozygous for the genes under study and produces the progeny genetically identical to it. Also known as true breeding plants, pure breeding varieties are mostly used in hybridization experiments.

For example, TT and tt are the pure breeding tall and dwarf varieties of pea that were used by Mendel for hybridization experiments. Continuous self-fertilization reduces heterozygosity and produces true breeding varieties over generations.
