Cloning

The video tutorial explains cloning, highlighting natural occurrences in bacteria and plants, and human reproduction through identical twins. It discusses laboratory cloning advancements, enabling genetic copies of plants and animals. Two main techniques are covered: embryonic cloning, where embryos are divided to create identical offspring, and fusion cell cloning, involving nucleus transfer to produce donor-identical offspring. Clones are genetically identical, with differences arising from environmental factors.

Explain the genetic relationship between cloned offspring and their donor.

What factors can cause differences between clones if they are genetically identical?
