The study of the laws and processes of biological inheritance.

• Heredity

• Genetics

• Zygotism

• Agriculture

The passing of traits from parents to offspring is called....

• Heredity

• Crossbreeding

• Selective Breeding

• Mutation

The sequence of nitrogen bases in the DNA molecule. Multiple variations.

• Cytosine

• Thymine

• Genetic Code

• Double Helix

Represents the actual genetic code. Cannot be changed by environment.

• Genotype

• Phenotype

• Nucleic Acid

• Double Helix

The organism’s physical or outward appearance. This is the part of the genotype the organism expresses or shows.

• Genotype

• Phenotype

• Nucleic Acid

• Double Helix

Organism having similar alleles or genes on the DNA molecule for a particular trait. (both genes are the same)

(BB)

• Heterozygous

• Homozygous

• Endothermic

• Exothermic

Organism having different alleles for a particular trait.

• Heterozygous

• Homozygous

• Endothermic

• Exothermic

A variation of a gene that will produce a certain phenotype, even in the presence of other alleles

Overrides the effect of the other gene. Represented by a capital letter.

• Dominant

• Recessive

• Codominant

• Incomplete Dominance

An allele that is only expressed when a dominant allele is not present. Represented by a lower case letter.

• Dominant

• Recessive

• Codominant

• Incomplete Dominance
