Inheritance and Genetic Variation Flashcards
Science
The carrier of genetic information in nearly all organisms; forms a double helix
DNA
A single, highly organized and structured piece of DNA
Chromosome
A version of a gene
Allele
The basic physical and functional unit of heredity made up of DNA
Gene
The variety of gene combinations that exist within a population
Genetic Variation
A characteristic that is passed from parent to offspring
Trait
Product of reproduction; a new organism produced by one or more parents
Offspring
A tool used to analyze the possible allele combinations of the offspring between two individuals
Punnett Square
The transfer of genetic information from parent to offspring
Heredity
An offspring resulting from the cross of two different species or subspecies
Hybrid
The exact genetic information carried by an individual
Genotype
The physical expression of a gene or set of genes; the appearance of an organism.
Phenotype
The reproductive process involving two parents whose genetic material is combined to produce a new organism different from themselves
Sexual Reproduction
The reproductive process that involves one parent and produces offspring identical to the parent
Asexual Reproduction
