- Inheritance of acquired Characteristics
- Sex Chromosome
- a the hypothesis that organisms' bodies change during their lifetimes by use and disuse and that these changes are inherited by their offspring
- Traits developed during a parent's lifetime could be passed to their offspring
- b the formation of new species as a result of evolution
- c ribonucleic acid; a nucleic acid that plays an important role in the production of proteins
- d (genetics) a chromosome that determines the sex of an individual
- e A pattern of evolutionary change involving the transformation of an entire population, sometimes to a state different enough from the ancestral population to justify renaming it as a separate species; also called phyletic evolution.
5 Multiple choice questions
- A stressful period in which few organisms of a population survive, resulting in loss of genetic variation in the population.
- Written by Charles Lyell, argued that geological processes observed in the present are the same as those that occured in the past
- in eukaryotic cells, a process of cell division that forms two new nuclei, each of which has the same number of chromosomes
- evolution resulting from small specific genetic changes that can lead to a new subspecies
- evolution on the smallest scale—a generation-to-generation change in the frequencies of alleles within a population
- an organic compound that is made of one or more chains of amino acids and that is a principal component of all cells
5 True/False questions
Plieotrophy → The physical traits that appear in an individual as a result of its gentic make up.
Systematics → change in a DNA sequence that affects genetic information
Alfred Russel Wallace → (The Origin of Species) a British naturalist, explorer, geographer, anthropologist and biologist. He is best known for independently proposing a theory of evolution due to natural selection that prompted Charles Darwin to publish his own theory.
Homology → similarity between two species that is due to convergent evolution rather than to descent from a common ancestor with the same trait
Forces of Evolution → 1. Mutation- changes in genetic code (source of new genetic diversity)
2. Migration- new traits are present (outsider comes in to breed)
3. Natural Selection- higher chance of surviving allows for more offspring
4. Random Genetic Drift- chance events/ changes, common in small populations
