Why does a person need to have two copies of the cystic fibrosis allele to have cystic fibrosis?
The allele is a carrier
The allele is recessive
The allele is dominant
What does heterozygous mean?
One dominant and one recessive allele
Two dominant alleles
Two recessive alleles
Why does a dominant allele create a higher probability of an offspring affected by a disease, such as cystic fibrosis?
Only one dominant parental allele is needed to produce a 50% chance of an individual being affected by a particular genetic condition
The parents always pass on these alleles
Dominant alleles are more common than recessive alleles
In a genetic diagram, how is a dominant allele shown?
As a bold letter
As a lowercase letter
As a capital letter
