GENE
GENE DEFINITION
the basic physical and functional unit of heredity, passed from parents to offspring
Trait definition
a distinguishing quality or characteristic, especially one belonging to a person.
Population definition
A group of organisms of the same species living in a particular area. They can interbreed and produce offspring.
Definition
refers to the differences among individuals of the same species, which can be caused by genetic (genotypic) or environmental (phenotypic) factors, or a combination of both
Definition
a statistical measure that indicates the proportion of individuals in a study or treatment group who are still alive for a specific period of time after a particular event
GENE TYPES
structural genes (coding for proteins), regulatory genes (controlling gene expression), and genes that code for RNA (that are not translated into proteins)
Examples of traits
Hair type
Where is population
everywhere
examples of variation
eye colour, hair colour, lobed or lobeless ears
What does a 30% survival rate mean?
people who have that cancer are, on average, about 30% as likely as people who don't have that cancer to live for at least 5 years after being diagnosed.
GENE EXAMPLE
hair color and skin color
Trait in a animal
characteristics that describe an animal's appearance, behavior, and how its body functions
How many population types are there
There is three
how many types of variation is there
4
What does a 95% mortality rate mean?
9.5 deaths per year in that entire population, or 0.95% out of the total.
How many genes are in a human
20,000
Types of traits
Openness, Conscientiousness, Extroversion, Agreeableness, and Neuroticism
why is population important
reducing disease risk, incidence and death, as well as improved quality of life for all individuals.
what are the types of variation
Direct, Inverse, Joint, and Combined
How do you calculate survival rate?
\(100\times (\text{Number\ alive\ at\ the\ end\ of\ a\ time\ period}\div \text{Number\ alive\ at\ the\ start\ of\ the\ time\ period})\)
What is the most famous gene
TP53. The tumour-suppressor, mutated in roughly half of all human cancers.
How are traits made
it took all your genes plus context (environmental factors)
What are the three types of population
uniform, random, and clumped
What is the variation of DNA?
reflects the differences in a person's DNA compared to other peoples' DNA
What does 95 survival rate mean?
95 of every 100 people diagnosed with that type of breast cancer are still alive five years after their diagnosis.
