Genetics

What is a phenotype

• The genetic make up (code)
• The physical trait

the passing of genetic traits from parent to offspring.

• heredity
• trait
• gene
• allele

having two of the same genes for the trait (sometimes called purebred).

• homozygous
• hetrozygous
• protein
• chromosome

having two different genes for a trait (sometimes called hybrid).

• protein
• homozygous
• heterozygous
• genotype
