The video tutorial explains incomplete dominance using carnations as an example. It describes how crossing red and white carnations results in pink offspring due to incomplete dominance, where neither allele is completely dominant. The tutorial establishes an allele key, verifies cross results, and solves a problem involving a cross between pink and white carnations. It concludes that a cross between pink and white carnations cannot produce red offspring, only pink and white.
