pedigree

These flashcards cover key vocabulary and concepts related to genetics, including pedigrees, inheritance patterns, and the influence of the environment on genetics.

Pedigree

A diagram that shows the genetic history of a family or group.

Autosomal Recessive Inheritance

A type of inheritance where two copies of an abnormal gene must be present for the disease to develop.

Autosomal Dominant Inheritance

A type of inheritance where only one copy of an abnormal gene is sufficient to cause the disease.

Karyotype

An organized picture of chromosomes used to check for genetic conditions.

Incomplete Dominance

A genetic situation where one allele does not completely dominate another allele, resulting in a new phenotype.

Codominance

A genetic phenomenon where both alleles are fully and equally expressed in the phenotype.

Gene-Environment Interaction

The effect of environmental factors on gene expression, leading to variations in phenotype.

Environmental Chemicals

Substances in the environment that can influence gene expression and may cause abnormalities.

Heterozygote

An individual who has two different alleles for a particular gene.

Phenotype

The observable characteristics or traits of an organism.
