Genetics 1
Short sections of DNA that provide the code to build proteins
genes
Genotypes consists of how many alleles?
2
What shapes are used in a pedigree for males and females?
Square for males
Circle for females
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 ______.
heterozygous
This model shows all of the possible outcomes of a genetic cross.
Punnett square
In a dihybrid cross, how many total boxes are in the Punnett square?
16
What happens when a recessive allele is paired up with a dominant allele?
It is a heterozygous genotype that one allele is hidden / doesn't show up
A word that means the numerical likelihood of something happening.
Probability
This type of organism has 2 dominant alleles for a trait.
Homozygous dominant
A change in an organism's DNA is called what?
mutation
When both alleles are fully expressed, like red and white cows making spotted cows, this is called:
What is codominance?
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
When traits blend together, like red flowers and white flowers making pink flowers, this is called:
What is incomplete dominance?
Shading in part or all of the shape.
