Genetics 1
Short sections of DNA that provide the code to build proteins
genes
Genotypes consists of how many alleles?
2
blood types
A, B, O, AB
This is an organism's genetic makeup, usually written using uppercase and lowercase letters.
Genotype
What did Gregor Mendel cross-pollinate in his genetics experiments?
pea plants
An organism with 2 different alleles (upper and lower case genotype) for a trait is called a ______.
Hybrid/heterozygous
This model shows all of the possible outcomes of a genetic cross.
Punnett square
What happens when a recessive allele is paired up with a dominant allele?
It is hidden / doesn't show up
A word that means the numerical likelihood of something happening.
Probability
A change in an organism's DNA is called what?
mutation
Using the Punnett Square below with Green being the dominant trait and yellow being the recessive trait. What is the probability the plant will be yellow?
G g
g Gg gg
g Gg gg
What is 50%?
This is the passing of traits from parent to offspring.
Heredity
This was the scientist who first began studying heredity and genetics, also known as the "Father of Genetics".
Gregor Mendel
Carriers or have the trait themselves or homozygous recessive or heterozygous
a genetic pattern where neither allele for a trait is completely dominant, resulting in a heterozygous offspring with a blended or intermediate phenotype
incomplete dominance
a genetic inheritance pattern where two different alleles in a heterozygote are fully and simultaneously expressed
codominance
