Genotype- the genetic info of an organism Phenotype- The genetic appearance of an organism.

Gene pool- different genes in a interbreeding population.

Genetic recombination- the process of recombining genes to produce new gene combinations that differ from those of
either parent.

Crossing-over- The exchange of DNA between homologous chromosomes.

Evolution- changes in a species genetic code overtime.

Acquired characteristics- traits that are changed during an organism's life span by the organism, according to Lamarck

Artificial selection- humans picking traits from nature that they find useful

Adaptation- a new characteristic that allows them to survive in their environment

Natural selection-LC-the process whereby organisms better adapted to their environment tend to survive and produce more offspring

Population- Amount of organisms in an environment

What do hox genes control? head to toe body plan development in organisms

What were Lamarck’s ideas about evolution? That organisms are able to acquire new characteristics based on using or not using various body structures, that organisms strive to become more perfect over time.

What does natural selection directly act on? an organism's characteristics (phenotype), not its alleles

List the five steps in the speciation of the Galapagos finches.
1. Founding of a new population
2. Geographic isolation
3. Changes in new population’s gene pool
4. behavioral isolation
5. Ecological competition

What does the crossing-over of chromosomes provide for organisms? Genetic variety

Final Exam Padlet Task
-Genetic drift is random, it just happens it can't really be controlled.

My chapter is important because well first it is basically everything, it's how things grow and develop into other species and evolve over time. Some of the factors that can bring about such changes are natural selection, mutation, random genetic drift, and migration into or out of the population. This helps show us how just everything around us changes and forms like genes being passed down and seeing different sides to it. One example is crossing over its like a genetic code/variety for living things.
