3. The Importance of Genetics
Genetics is the study of the laws and processes of biological inheritance from the parents of an offspring
You can track the transfer of traits from parents to young
You can even go back many generations of recorded breeding
This is why purebred animals have documented pedigrees to validate
Heredity is the passing of traits from parents to offspring

4. The Importance of Genetics
Chromosome is a threadlike structure containing the genetic material
The genetic material in a chromosome is called the Genome of an animal
Deoxyribonucleic Acid (DNA) is a protein-like nucleic acid on genes that controls inheritance
Genetic Code is a sequence of nitrogen bases

5. Genotype and Phenotype
The genetic code of an animal is predetermined by the genetics of its parents
Determines how the animal grows, lives and possibly even dies
The genetic code of an animal is called its Genotype
This is not influenced by its environment
The physical appearance of an animal is called its Phenotype
This can be influenced by its environment

6. Homozygous & Heterozygous
The alleles (or genes) for a trait may or may not match
Homozygous animals would pass only one side of a trait
Pass on only one side of a trait
Horns or no horns
AA or aa
Heterozygous animals have different alleles for a trait
May or may not pass on a trait Aa
