Final exam review

Unit 4 Genetics

100

This is a nitrogenous base that DNA does NOT have, but RNA does. 

Uracil

200

This is the name of a group of three nucleotides. 

codon

300

If an organism has 100 chromosomes in a somatic cell, then this is how many it would have in its gametes. 

50 (half of somatic cell chromosomes) 

400

This is where translation takes place and the product. 

Ribosomes in the cytoplasm; Polypeptide chain/protein

500

This is the end result of meiosis. 

Four haploid cells (not identical) 

Unit 5 Heredity

100

This is what we call the actual inherited alleles a person has. 

Genotype 

200

This is the genotype a person needs in order to show a recessive trait. 

Homozygous recessive. 

300

This is the inheritance pattern name and result when two genes are both dominant. 

Codominance; the traits show up separately.  

400

When two genes are commonly inherited together, they follow this pattern of inheritance. 

Linked genes 

500

This is the inheritance pattern when a trait is affected by the interaction of many genes. 

Polygenic trait 

Unit 6 Evolution

100

This is the type of evolution that happens on a small scale, within one population. 

Microevolution

200

This is the hierarchy of classification, starting at the most broad taxonomy level to the most specific. 

Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species

300

This is what we call a trait that helps an organism survive in its environment. 

an adaptation

400

This is an example of something that increases genetic variation. 

(more than one answer) Mutations, gene flow, crossing over 

500

This is what we call structures that are considered to have no apparent function.

Vestigial structures

Unit 7 Ecology

100

This is a characteristic of a living thing. (more than one answer) 

metabolism, made of cell(s), reproduces, grows, contain genetic material, respond to a stimulus, adapt  

200

This makes up a scientific name. 

Genus species 

300

This is an example of a biotic factor that affects the size of a population. 

Disease, predation, competition 

400

This is the main difference between parasitism and predation. 

Parasites do not kill their host, they just feed off of them alive. 

500

This describes a niche. 

All an organism needs/uses in their environment. 

Miscellaneous

100

This is the type of succession that a forest fire leads to.  

secondary succession 

200

This is the definition of population. 

A group of the same species in a defined space.

300

This is the inheritance pattern name and result when two genes are neither dominant nor recessive. 

Incomplete dominance (blend together) 

400

This is what ultimately/mainly causes genetic diversity.

Mutations 

500

These are mutations that impact a whole group of genes, meaning along a large segment of DNA. 

Chromosomal mutations
