Unit 4
This process explains how certain traits become more common in a population because they help organisms survive and reproduce.
Natural selection
These types of genetic changes can result in new traits, which may be beneficial, harmful, or neutral.
mutations
This tool is used to predict the likelihood of offspring inheriting specific traits from their parents.
Punnett Square
what is the highest point of a wave?
crest
who is the original singer for the hit Christmas song, "All I want for Christmas is you"
Mariah Carey
type of genetic drift that occurs when a population experiences a dramatic reduction in size due to a sudden event, such as a natural disaster, disease, or human activity.
bottleneck effect
if capital B means brown eyes and lower case b is blue eyes, what color eyes would show for the genotype Bb
brown eyes
What is the difference between dominant and recessive traits?
Dominant traits are expressed when at least one dominant allele is present, while recessive traits are expressed only when both alleles are recessive.
What is the unit of frequency in wave mechanics?
Hertz
The actor, Macaulay Culkin, stars in Home Alone. What is his name in the movie?
Kevin
The pairing of identical alleles for a trait creates this kind of genotype.
Homozygous
A __________ mutation involves the addition or deletion of a nucleotide, causing a shift in the reading frame.
frameshift
Organisms that inherit two different alleles for a gene are called __________.
heterozygous
How do you calculate speed of a wave?
frequency x wavelength
Which reindeer’s name begins with the letter 'B'?
Blitzen
the observable physical traits or characteristics of an organism is called a ______
phenotype
A mutation that changes only one nucleotide in DNA is called a __________ mutation.
point
a phenomenon in population genetics where a new population established by a small number of individuals from a larger population carries only a fraction of the genetic diversity of the original population
founder effect
________ occurs when light waves bend as they pass from one medium to another due to a change in speed.
refraction
What is the name of the Grinch’s dog?
Max
Each gene is made up of a specific sequence of __________, which provides instructions for making proteins.
DNA
________ are the building blocks of proteins, which are assembled based on the instructions in genes.
amino acids
_______ are characteristics or features of an organism that can be inherited, acquired, or influenced by the environment.
Traits
What causes the bending of light when it moves from one medium to another?
The change in speed of light as it enters a different medium.
In "Elf," what are the four main food groups for elves?
Candy, candy canes, candy corns, and syrup
