Unit 6
This process produces somatic cells
What is mitosis
An organism with the genotype "Rr" would be described as
What is heterozygous
All of the members of a particular species that live in one area are called
What is a population
Which type of symbiotic relationship involves one species benefitting, while the other is neither helped or harmed. An example of this is the remora and a shark
What is commensalism
This is the name of an organism that has been taken from its native habitat and transplanted to a new environment
What is a nonnative species
These 4 phases make up the process of Mitosis
What is prophase, metaphase, anaphase, and telophase (PMAT)
This process involves breeding dissimilar organisms to bring together desired characteristics
What is hybridization
What is the original source of all variation
What are mutations
A whale pelvis and femur are an example of which structure
What is a vestigial structure
This term refers to the average year after year conditions of temperature and precipitation in a particular region
What is climate
These fibers help separate sister chromatids during mitosis
What are spindle fibers
This inheritance pattern is identifiable by the trait affecting a similar number of males and females and skipping a generation,
What is autosomal recessive
Which type of survivorship curve represents the survival of the human population
What is Type I
What causes unrelated organisms to develop similar structures with similar functions
What are similar selective pressures
What is UV light
Two chromosomes that carry the same information (i.e. the gene for hair color). One came from your mother and one from your father
What are homologous chromosomes
A cross of a black chicken and a white chicken produces all black and white speckled offspring. This type of inheritance is known as
What is Codominance
What did Darwin consider to be a "detailed record of evolution"
What are fossils
A 12 inch proboscis (mouth) on a moth and the 12 inch nectary of an orchid is an example of which type of evolution
What is coevolution
A wide base in an age structure diagram indicates this
What is a high birth rate
This process involves homologous chromosomes trading pieces. This process is vital to the survivability of a species because it increases genetic variability. This process occurs in Prophase I of Meiosis.
What is crossing over
This is the name for an organism with a gene from another organism
What is a transgenic organism
Three similar species of orchid all live in the same rain forest. Each species opens and releases pollen only on a single day. Because the three species release pollen on different days, they cannot pollinate one another. This is an example of which type of isolaton.
What is temporal isolation
This type of evolution results in analogous structures
What is convergent evolution
A series of predictable changes that occur in an ecosystem over time
What is ecological succession
