DNA & Genes
This molecule contains the instructions for life.
DNA
Characteristics passed from parents to offspring.
Traits
Reproduction involving one parent.
Asexual Reproduction
When one allele completely hides another.
Dominance
Each parent provides this many alleles for each trait.
One
These are segments of DNA that control traits.
Genes
The passing of traits from parents to offspring.
Hereditary Inheritance
Reproduction involving two parents.
Sexual Reproduction
When two alleles blend together.
Incomplete Dominance
The location where chromosomes are found.
Nucleus
DNA is arranged into these structures inside the nucleus.
Chromosomes
Different versions of a gene.
Alleles
The joining of egg and sperm cells.
Fertilization
When both alleles are fully expressed.
Codominance
Why siblings may look different from one another.
Genetic Variation
The order of DNA bases is called this.
Sequence
An allele that always shows when present.
Dominant Allele
Offspring from this type of reproduction are genetically identical to the parent.
Asexual Reproduction
When many genes control one trait.
Polygenic Inheritance
This controls how traits appear in an organism.
Gene Expression
The process by which genes produce traits.
Gene Expression
An allele that only shows when two copies are present.
Recessive Allele
This type of reproduction increases genetic variation.
Sexual Reproduction
Skin color and height are examples of this inheritance pattern.
Polygenic Inheritance
The main advantage of genetic variation.
Increased Survival/ Adaptation
