Vocab 8 - Genetics & Heredity

The study of how traits are inherited through the actions of alleles

• Hereditary

• Genetics

• Genotype

• Polygenic Inheritance

The passing of traits from parents to offspring

• Hereditary

• Genetics

• Genetic Engineering

• Recombinant DNA

An alternate form a gene may have for a single trait- can be dominant or recessive

• Heterozygous

• Phenotype

• Homozygous

• Allele

Describes a trait that covers over, or dominates another form of that trait(written in uppercase letters)

• Recessive

• Genotype

• Hybrid

• Dominant

Describes a trait that is covered over, or dominated by another form of that trait and seems to disappear ( written in lowercase letters)

• Genetics

• Dominant

• Recessive

• Hereditary

Describes an organism with two different alleles for one trait

• Heterozygous

• Homozygous

• Multiple Alleles

• Polygenic Inheritance

Describes an organism with two alleles that are the same for one trait

• Homozygous

• Hybrid

• Heterozygous

• Gene Therapy

An organism's genetic make-up (Gene-type - letters)

• Phenotype

• Punnett Square

• Genotype

• Gene Therapy

The outward physical appearance/ behavior of an organism (what the letters mean)

• Genotype

• Phenotype

• Pedigree

• Genetic Engineering

An offspring given different genetic information for a trait from each parent (opposite of purebred)

• Pedigree

• Incomplete Dominance

• Polygenic Inheritance

• Hybrid
