Evolution and Natural Selection Flashcards
Things like inherited traits, mutations, chromosome abnormalities that can affect the growth of an organism
Genetic Factors
A complex molecule containing the genetic information that makes up the chromosomes
DNA
The first generations of offspring of a genetic cross. ex. first people, first generation
F1 Generation
A genetic trait passed from a parent to a child that is more likely to be expressed
Dominant trait
A genetic trait that is not shown when a dominant gene is present
Recessive trait
a tightly wound bundle of DNA and proteins found in the nucleus of most living cells
chromosome
An organism in the earliest stage of development
embryo
a genetically determined condition or characteristic ex. blue eyes, red hair
genetic trait
to receive genetic information and traits from a parent or parents
inherit
conditions such as: Climate, pollution, food supply, clean water, predators, or natural disasters that can affect the growth of an organism or species
environmental factor
the basic unit of heredity in a living organism; a segment of DNA or RNA
Gene
change in a DNA sequence that affects genetic information
mutation
behaviors such as drug/tobacco/alcohol use, proper hygiene, medical check ups, sleep, that can affect the growth of an organism
lifestyle choices
theory stating that natural variation among organisms that make them the best adapted to their environment, live and reproduce better. “survival of the fittest”
Natural selection
Change in a kind of organism over time; process by which modern organisms have descended from ancient organisms
evolution
