Genetics
Mitosis
A kind of cell reproduction that results in 2 daughter cells with the same kind and number of chromosomes as the parent nucleus
Genotypes
The genetic features of an organism
Natural Selection
The process when organisms better adapted to their environment live longer
Artificial Selection
The process in which humans select certain features in organisms
Fossils Definition
The remains or impression of a prehistoric organism preserved in petrified form or as a mold or cast in rock
Meiosis
A type of cell division that results in 2 daughter cells that each have half the number of chromosomes as the parent nucleus
Phenotype
The physical traits of an organism
Migration
The movement of animals into or out of different groups
Cloning
To replicate a fragment of DNA placed in an organism
Fossil Types
Trace fossil, Amber fossil, Molds fossil, Body fossil
Types of cells Mitosis occurs in
Punnett Squares
A diagram of a grid, usually four boxes, that helps determine the possible traits for offspring
Mutation
The changing of the structure of a gene
GMO
A plant, animal, or microbe in which one or more changed have been made to a genome
Fossil Uses
Explains what happened long ago, and fossil fuels
Types of Cells Meiosis occurs in
Meiosis occurs in Germ Cells
Homozygous
The same alleles
Genetic Drift
The change in frequency of an existing gene variant due to random chance
Selective Breeding
The process of modifying the characteristics of living things
Law of Superposition
States that the oldest layers of rock are at the bottom, and the younger layers of rock are at the top
Differences Between Plant and Animal Cells
Plant cells have a cell wall and large central vacuole. Animal cells have centrioles and lysosomes
Heterozygous
Different alleles
Evolve
To gradually develop, especially from a simple form
Gene Therapy
A technique that modifies a person's genes to treat or cure disease
