What is the difference?

Heredity – passing of traits from parent to offspring

Traits – the physical, social, and emotional qualities of an organism Example – blue eyes, tall, hates carrots

Dominant Trait – Stronger trait that will overtake a recessive trait

Recessive Trait – Weaker trait that is hidden by a dominant trait

Alleles – all the possible choices for a characteristic Example – eye color – blue, brown, gray, green

Genotype – the pair of genes an organism has (one allele from each parent)

Phenotype – the trait that can be seen

How the genes code for a specific trait.

If the trait is dominant it uses a capital letterExample – Tall (T)

If the trait is recessive it uses the same letter but lower caseExample – short (t)

Genotypes always have two letters – one for dad and one for mom

Homozygous - an individual that has the same type of gene from each parent. (Ex. BB or bb)

Heterozygous – an individual that has different gene types (one from each parent). (Ex. Bb)

Homozygous dominant – the genes only have the dominant trait in its code. Example – Dominant Tall – TT

Homozygous recessive – the genes only have the recessive trait in its code. Example – Recessive short – tt

Heterozygous – the genes are mixed code for that trait. Example – hybrid Tall -- Tt

The outward appearance of the trait.

How an organism looksHow an organism actsHow an organism feels

Genotype – deals with GENE CODE.

Phenotype – deals with looks you can take a PHOTO with.
