This term describes an organisms genetic makeup
genotype
This tool is used to predict offspring outcomes.
Punnett Square
This law states that alleles separate during gamete formation.
The Law of Segregation
When two alleles blend to create a new phenotype.
Incomplete dominance
This genetic test is often used to determine biological relationships between individuals
DNA test
This refers to the observable traits of an organism.
phenotype
In a cross Aa × Aa, this is the probability of aa offspring.
25%
This law explains why traits are inherited independently.
Law of Independent Assortment
When both alleles are fully expressed in an organism.
Codominance
This rare condition causes people to have an extra finger or toe.
polydactyly
An allele that is masked unless two copies are present.
Recessive
The genotype outcome of Aa × Aa
25% AA 50% Aa 25% aa
A cross involving two different traits is called this.
Dihybrid cross
If a cow is white with red spots, what type of inheritance is it?
Codominance
This famous X-linked trait can make it hard to distinguish red from green.
Color blindness
Having two identical alleles for a trait.
Heterozygous
How many offspring are heterozygous and homozygous recessive
2
In guinea pigs, black fur (B) is dominant over white fur (b).
A heterozygous black guinea pig is crossed with a white guinea pig:
Bb × bb
What percentage of the offspring will have white fur?
50%
Traits controlled by more than one gene are called this.
Polygenic inheritance
This breed of cat is known for having no fur due to a mutation.
Sphynx cat
An organism with two different alleles for a trait.
Heterozygous
In pea plants, tall (T) is dominant over short (t), and green pods (G) are dominant over yellow pods (g).
Two plants that are heterozygous for both traits are crossed:
TtGg × TtGg
What is the probability that an offspring will be short with yellow pods?
1 out of 16
This scientist is known as the “Father of Genetics.”
Gregor Mendel
A trait influenced by both genes and environment (like height).
Complex trait
In this movie, dinosaurs are recreated using preserved DNA.
Jurassic Park
