The study of how cells control gene activity without changing the DNA sequence

The basic physical and functional unit of hederdity

Made up of Organisms

The study of genes, genetic variation and heredity in organisms

Is the complete set of genetic material

Alleles or variants in an induvidual

An individual’s observable traits, such as height,

A type of cell division in sexually reproductive organisms that reduces the number of chromosomes in gametes

The reproductive cell of a plant or animal

The union of 2 gametes

The presence of 2 complete sets of chromosomes in an organisms cells with each parent of contributing a chromosome pair

The presence or a single set of chromosomes in an organism cells

A cell that separated from the immature ovum during metosis and that continues a nucleus produced in the first or second division of metosis but very little cytoplasm

A specific charachtistic of an individual

Paired chrosmosome

One of the numbered chromosomes as opposed to the sex chromosomes

A type of chromosome involved in sex determination

An indivudiual who “carries” and can pass on to offspring a genome veriant

Characteristics that are influenced by genes carried on; the sex chromosome

A type of inherentence in which two versions (allels) of the same gene are expressed

A type of inheritance in which 2 versions (allels) of the same gene are expressed seperatly to yield different traits in an individual

A characteristic such as height or skin color that is influenced by 2+ genes.

any cell of a living organism other than the reproductive cells.
