Autosome

A chromosome that carries information about an organism ex) hair color, eye color etc, but does not determine sex

Centromere

Structure in the center of a chromosome that holds 2 chromatids together and allows chromosomes to connect to spindle fibers

Chromatid

1 of the 2 condensed strands of a chromosome; has an exact copy

Sex Chromosome

Determines if an organism will be male or female; either X or Y

Diploid

A cell that has 2 sets of genetic information, one from a mother, one from a father

Haploid

Having 1 set of chromosomes; sperm, egg or bacterial cells

Homologous Chromosomes

Having the same type of information in 2 different chromosomes; same size and shape

Karyotype

A picture of an organisms chromosomes, can be used to determine the sex or genetic disorders

Chromosome

rod shaped structure in a cell made of DNA and protein

Meiosis

When a dipliod reproductive cell goes through divisions to decrease the number of chromosomes by half

Gametes

Reproductive cells that are haploid (egg and sperm cells)

Genetic Recombination

Genetic material that has been mixed, producing unique offspring

Independent Assortment

Random distribution of genes on homologous chromosomes during anaphase I of meiosis I, resulting in genetic recombination.

Spermatogenesis

The process of meiosis that produces sperm cells.

Oogenesis

The process of meiosis that produces 1 egg cell and 3 polar bodies.

Asexual Reproduction

Producing offspring from one parent. Offspring are genetically identical to the parent.

Sexual Reproduction

Producing of offspring by the joining of a sperm and egg cell, which are products of meiosis.

Synapsis

Pairing of homologous chromosomes during prophase I in meiosis I.

Tetrad

A pair of homologous chromosomes that come together during meiosis

Crossing-over

When parts of chromatids break off and reattach to their homologous

Metaphase

Chromosomes line up in the center of the cell; karyotypes are often made by looking at this stage

Mitosis

The division of a cell's nucleus

Cell Cycle

The continuous events that make up the life of a cell

Cytokinesis

the division of the cytoplasm of a cell, occurs during cell reproduction

Interphase

A stage of cell growth (G1), maturation, DNA replication (S), and preperation for cell division (G2)

Prophase

The stage during which chromosomes condense, spindle fibers are formed, and the nuclear membrane breaks down

Anaphase

Chromosomes move apart to opposite sides of the dividing cell by separating at the centromere

Telophase

Cell membrane pinches in; Nuclear membrane starts to form, chromosomes unravel, spindle fibers disassemble

Binary Fission

The simple way in which prokaryotic organisms produce offspring cells
