Genetics Vocab
The passing of traits from parents to offspring.
What is Heredity?
What letter represents a recessive allele?
What is a lowercase letter (b)?
What is the purpose of a Punnett square?
To predict possible genetic combinations of offspring.
What is genotype?
The genetic makeup of an organism.
In Bb × Bb, what percentage of offspring will be BB?
What is 25%
A different form of a gene.
What is an Allele?
What letter represents a dominant allele?
What is a capital/uppercase letter (D)?
What goes on the outside of a Punnett square?
Alleles from each parent
What is phenotype?
The observable appearance or trait of an organism.
In Bb × Bb, what percentage will show the dominant phenotype?
What is 75%
A characteristic or feature of an organism.
What is a Trait?
If B is dominant and b is recessive, which trait will BB show?
What is a dominant trait?
Complete the cross: BB × bb. What are the offspring genotypes?
100% Bb.
Is Bb homozygous or heterozygous?
In Bb × Bb, what is the genotype ratio?
1 BB : 2 Bb : 1 bb.
Structures made of DNA that carry genetic information.
What are Chromosomes?
What must an organism inherit to show a recessive trait?
Complete the cross: Bb × Bb. What are the possible genotypes?
BB, Bb, Bb, bb.
Is TT homozygous or heterozygous?
In Bb × bb, what is the phenotype ratio?
1 dominant : 1 recessive.
A section of DNA that contains instructions for an inherited trait.
What is a gene?
Can a heterozygous organism show a dominant trait?
Yes, because one of its alleles are dominant.
Complete the cross: Bb × bb. What percentage of offspring will be bb?
What is 50%
An organism has the genotype bb. What is its genotype classification?
What is Homozygous Recessive?
In BB × Bb, what percentage of offspring will show the dominant trait?
What is 100%?
