Vocabulary
A group of individuals of the same species that can interbreed with one another
Population
If you have allele frequencies of A = 0.7 and a = 0.3, what is the genotype frequency of heterozygous individuals in the population? (assume the population is in HWE)
Aa = 0.42
Give an example of... a cause of a genetic mutation
Random copying errors, chemical agents, radiation, UV light, free radicals
What character does Steve Carell play in "The Office"?
Michael Scott
The physical expression of the genes of an organism
Phenotype
What is the equation for allele frequency (Hardy-Weinberg)?
p + q = 1
The observed frequency of homozygous dominant individuals in a HWE population is 0.81. What is the allele frequency of A?
A = 0.9
Give an example of... intrasexual selection
Male kangaroos fighting over a female (any example of males fighting for females)
When is "National Ice Cream" month?
July
Intersexual selection
Fill in the blank: Hardy-Weinberg is the _______________ for evolution.
A population of 1200 butterflies have the following genotype frequencies for wing color:
GG = 0.49
Gg = 0.42
gg = 0.09
How many butterflies are homozygous recessive?
gg = 108 butterflies
Give an example of... an environment where disruptive selection might be favored
A diverse environment (a snowy region with patches of mud and grass)
Who was the first women to win a Nobel Prize?
Marie Curie
Genetic change in the gene pool of a population from generation to generation
Microevolution
Why does microevolution occur?
Characteristics that give a survival advantage to an organism make it more likely to survive and reproduce (some genotypes give greater reproductive success)
Use the whiteboard to draw a Punnett Square. The male should be heterozygous for a trait and the female should be homozygous for the same trait.
a a
A Aa Aa
a aa aa
Provide 2 of the 5 Hardy-Weinberg assumptions
Large population, random mating, no selection, no mutation, no migration
What is the tiny plastic piece at the end of a shoelace called?
An aglet
Individuals preferentially mate with individuals of a particular genotype
Non random mating
Why does inbreeding favor homozygosity?
Inbreeding increases the chances of inheriting deleterious recessive alleles because more genetic information is shared between the parents
In a population that is in HWE, a dominant allele, H, has a frequency of 0.6. What is the frequency of the hh genotype?
hh = 0.16
Give an example of... an event that might yield a bottleneck effect
Any natural or human disaster (disease, earthquake, volcano exploding)
How old are the horses that run in the Kentucky Derby?
3 years old
