All ([[sexual reproduction|sexually reproducing]]) organisms contain their genetic information in paired form. Each offspring inherits half its genetic information from its mother, and half from its father. So there are two [[gene|genes]] at a given position (locus, plural loci) coding for a particular characteristic. An organism can be [[heterozygous]] at a given locus, meaning it carries different forms ([[allele|alleles]]) of this gene... So there is no problem for creationists explaining that the original created kinds could each give rise to many different varieties. In fact, the original created kinds would have had much more heterozygosity than their modern, more specialized descendants. No wonder [[Francisco J. Ayala|Ayala]] pointed out that most of the variation in populations arises from reshuffling of previously existing genes, not from mutations. Many varieties can arise simply by two previously hidden [[recessive allele|recessive alleles]] coming together. However, Ayala believes the genetic information came ultimately from mutations, not creation. His belief is contrary to [http://creation.com/information-theory-questions-and-answers information theory], as shown in [http://creation.com/refuting-evolution-chapter-9-is-the-design-explanation-legitimate chapter 9 on ‘Design’].<ref>http://creation.com/refuting-evolution-chapter-9-is-the-design-explanation-legitimate</ref>}}
