Evolution
What is the raw material of evolution
Mutations
This type of speciation occurs when the organisms live in the same area
Sympatric speciation
Does meiosis or Mitosis produce identical copies?
Mitosis
Capital letters
Define Gene flow
When individuals from 2 or more populations move between these populations sharing genes
This type of speciation occurs when species are separated by a physical barrier
Allopatric speciation
What is an allel
Alternative form of a gene
What is a phenotype?
What you physically see
What evidence is there for evolution? (4 things)
Artificial selection
Fossils / Morphological similarities
Genetic similarities
Developmental similarities
We refer to this type of natural selection when traits on opposite end of the trait spectrum are selected for.
What is DNA
a molecule that contains genetic instructions for
producing proteins (or heritable traits)
What is a Homozygous trait vs a Hterozygous trait
Homozygous- either both allels are dominate or both are recesive (ex. OO or oo)
Heterozygous- one resezive and one dominate trait. (ex. Oo)
What is natural selection?
The natural process where less fit organisms don't pass down their genetic material to the next generation, meaning the more fit organisms produce more offspring and pass on their genetic information
Directional Selection
What are body cells called?
What type of cells produce a gamete?
Stomatic Cells are body cells.
Germ cells produce gametes
What is independent assort ment
Allels of non homologous chromosomes move indipendently of another into gametes
What is the difference between a genetic bottle neck and the founders effect
In the founders effect a new population is FOUNDED by a part of a larger population that got separated.
What are the three ways to determine a species?
Breeding isolation
Morphological differences
Genetic differences
What is the law of segregation
When allels of homologouse chromosomes sort to diffrent gametes
What is crossing over
Swapping of homologous chromosome segments
