Genetics

The set of instructions that is found in DNA

• phenotype

• meiosis

• trait

• gene

The different variations of a gene. Letters are used to represent each version.

For example: B - brown or b - blue

• genes

• alleles

• trait

• phenotype

The pairing of two different alleles. Also called hybrid.

Example is Tt.

• homozygous

• heterozygous

• dominant

• genotype

The pairing of two of the same alleles. Also called purebred. Example: TT or tt

• recessive

• genotype

• homozygous

• heterozygous

An organism's physical appearance of a trait.

It is what you see.

• phenotype

• genotype

• trait

• dominant

The genetic makeup of an organism.

It is represented using pairs of letters such as TT, Tt, or tt.

• DNA

• genes

• phenotype

• genotype

The trait that always shows itself.

Represented using a capital letter.

• gene

• mitosis

• dominant

• recessive

The trait that is hidden by a dominant.

It is represented with a lowercase letter.

It only shows up if you get two lowercase letters.

• alleles

• genotype

• dominant

• recessive

When one allele is not dominant over another, resulting in a blended phenotype for heterozygous offspring is considered....

• Incomplete Dominance

• Codominance

When one allele is not dominant over the other, resulting in both traits expressed in a heterozygous individual.....

• Incomplete Dominance

• Codominance
