Introduction to Basic Genetics

Genes come in matched pairs and a puppy inherits half of their set from their mother and the other half from their father, creating their own unique set of matched pairs. Sometimes a mutation can occur that alters one of the genes carried by a parent and this gene becomes defective. The defect can then be passed on just like a healthy gene. This can lead to a genetic illness. There are many ways that defective genes can be inherited and it must be remembered that genetics is new and scientists are only at the beginning of their journey to understand how inheritance works. The following is a very simple introduction to some of the basic forms of inheritance. To learn more, go to this website, it is packed with detail and quite easy to navigate.
