Large-scale mutations. 1  Copy number variation (CNV) is a type of mutation where large chunks of DNA are inserted, repeated or lost. 2  Duplication of genes. 3  Deletions of large regions of the chromosome. 4  Loss of one copy of a gene in an organism that previously had two copies.  Loss of both copies of the same gene.
Tulips are spring-blooming perennials that grow from bulbs. Depending on the species, tulip plants can be between 4 inches (10 cm) and 28 inches (71 cm) high. The tulip's flowers usually bloom on scapes with leaves in a rosette at ground level and a single flowering stalk arising from amongst the leaves.
Seeds form after the flowers have been pollinated and have faded. Tulips that grow from seed have the genetic information from two plants. When honeybees and other pollinators alight on one tulip plant, their legs are coated with pollen. When they travel to another plant, some of the pollen falls off.
