Question

What causes variation in multicellular organisms?

Answer 1

Hey There! Multicellular organisms arise in various ways, for example by cell division or by aggregation of many single cells. The variation occurs both within and among populations, supported by individual carriers of the variant genes. Genetic variation is brought about, fundamentally, by mutation, which is a permanent change in the chemical structure of chromosomes. Genetic recombination also produces changes within alleles.
