No — that statement is incorrect.
- An organism with two identical alleles for a trait is called homozygous (e.g., BB or bb).
- A hybrid usually refers to an organism produced by crossing genetically different parents and, in genetic terms, is typically heterozygous for a given gene (two different alleles, e.g., Bb).
- “Hybrid” can also mean an interspecific or intervarietal cross (e.g., mule = horse × donkey, or many plant hybrids).
So: identical alleles = homozygote; different alleles (from a cross) = heterozygote/hybrid.
