Unit 4 Genetics
This is a nitrogenous base that DNA does NOT have, but RNA does.
Uracil
This is what we call the actual inherited alleles a person has.
Genotype
This is who came up with the theory of natural selection.
Charles Darwin
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
This makes up a scientific name
Genus species
This is the name of a group of three nucleotides.
codon
This is the genotype a person needs in order to show a recessive trait.
Homozygous recessive.
This is what we call a trait that helps an organism survive in its environment.
an adaptation
This is the hierarchy of classification, starting at the most broad taxonomy level to the most specific.
This is the type of succession that a forest fire leads to.
secondary succession
This is where translation takes place and the product.
Ribosomes in the cytoplasm; Polypeptide chain/protein
This is the complex inheritance pattern name and result when two alleles are both dominant.
Codominance; the traits show up separately in phenotype.
This is the type of evolution that happens on a small scale, within one population.
Microevolution
This is the main difference between parasitism and predation.
Parasites do not kill their host, they just feed off of them alive.
This is the definition of population.
A group of the same species in a defined space.
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)
When two genes are commonly inherited together, they follow this pattern of inheritance.
Linked genes
If an ecosystem is overpopulated, what will happen?
Competition will occur
This describes a niche.
All an organism needs/uses in their environment.
This is the complex inheritance pattern name and result when two alleles are neither dominant nor recessive.
Incomplete dominance (blend together for phenotype)
This is the end result of meiosis.
This is the inheritance pattern when a trait is affected by the interaction of many genes.
Polygenic trait
This is an example of something that increases genetic variation.
(more than one answer) Mutations, gene flow, crossing over
This is an example of a biotic factor that affects the size of a population.
Disease, predation, competition
These are mutations that impact a whole group of genes, meaning along a large segment of DNA.
Chromosomal mutations
