Explanation

A backcross involves crossing a hybrid offspring with one of its parental types. This differs from a test cross (cross with homozygous recessive), monohybrid cross (single trait heterozygotes), or dihybrid cross (two traits). Backcrossing is used to recover parental genotypes or introgress traits.
