Question

State whether the following statement is true or false.

Barring mutation, a pure line is expected to breed true to type.

Answer 1

This statement is true.

Explanation:

A pure line consists of homozygous individuals for a particular trait, so when these individuals self-pollinate or breed among themselves, they consistently produce offspring with the same phenotype as the parent. This stability and uniformity occur because there is no genetic variation at the locus controlling the trait, hence the offspring “breed true to type” unless a mutation occurs to alter the genotype or phenotype.
