|
What is DNA?
|
A chemical inside cells that contains heredity information and controls how an will look and function
|
|
|
What is mitosis?
|
Cell division process in which DNA in the nucleus is duplicated and the nucleus divides into two nuclei that contains the same genetic information
|
|
|
What is meant by sexual reproduction?
|
A type of reproduction in which a new organism is produced from the DNA of two sex cells (egg and sperm)
|
|
|
cloning
|
Making copies of organisms, each of which is a clone that receives DNA from only one parent cell
|
|
|
What is meant by asexual reproduction?
|
A type of reproduction, such as budding or regeneration, in which a new organism is produced from a part of another organism by the process of mitosis
|
|
|
sex cells
|
specialized cells--female eggs and male sperm--that are produced by the process of meiosis, carry DNA, and join in sexual reproduction
|
|
|
meiosis
|
process in which sex cells are formed in the reproductive organs; involves two divisions of the nucleus, producing four sex cells, each having half the number of chromosomes as the original cell
|
|
|
fertilization
|
process in which sperm and egg join, resulting in a new organism
|
|
|
heredity
|
passing on of traits from parents to offspring
|
|
|
genetics
|
study of how traits are passed from parents to offspring
|
|
|
gene
|
small section of DNA on a chromosome that carries information about a trait
|
|
|
variation
|
inherited trait that makes an individual different from other members of the same species and results from a mutation in the organism's genes
|
|
|
mutation
|
change in a gene or chromosome that can result from something in the environment or an error in mitosis or meiosis; can be harmful, neutral, or beneficial, and adds variation to the genes of a species
