Basic Genetics

having two different genes for a trait. (example Hh)

• homozygous
• heterozygous
• dominant
• purebred

having two of the SAME genes for a trait (example HH or hh)

• homozygous
• heterozygous
• recessive
• dominant

the chances of somethings happening (example 1 in 4)

• genotype
• phenotype
• alleles
• probabiltiy

an organisms genetic make up

• phenotype
• genotype
• heredity
• recessive

an organisms appearance or other detectable characteristics

• phentoype
• genotype
• recessive
• dominant

one set of instructions for an inherited trait. section of DNA that is responsible for a specific trait.

• gene
• allele
• heredity
• genotype

a trait that reappears in the 2nd generation after disappearing in the first generation when parent with different traits breed. (the one that vanishes)

• gene
• phenotype
• dominant
• recessive

the trait observed in the first generation when parents that have different traits are breed. (the stronger trait)

• recessive
• dominant
• gene
• phenotype

the passing of genetic traits from parent to offspring

• allele
• gene
• heredity
• homozygous

a genotype with alleles of  "HH" would result in a ___________ trait.

• dominant
• recessive
