Genetics Quiz

What term is used to describe traits that are found on the X chromosome?

• Allele

• Purebred

• Genotype

• Sex-Linked Traits

What is the term for having one recessive allele for a genetic disorder and not showing the trait?

• Heterozygous

• Carrier

• Homozygous

• Phenotype

What does the term 'Genotype' refer to?

• The physical expression of genes

• Traits that are found on the X chromosome

• The genes that an individual has for a trait

• A version of a gene (represented with 1 letter)

What is the definition of 'Allele'?

• Having two of the same exact alleles ex. EE

• A version of a gene (represented with 1 letter)

• Another term used to describe homozygous

• When the genotype has one dominant and one recessive allele

What does 'Homozygous' mean?

• Having 1 recessive allele for a genetic disorder

• Determining the offspring using 1 trait for a Punnett square

• Another term to describe homozygous

• Having two of the same exact alleles ex. EE

What is the term for determining the offspring using 1 trait for a Punnett square?

• Monohybrid

• Multiple Alleles

• Dihybrid cross

• Polygenic inheritance

What does 'Multiple Alleles' refer to?

• When a trait has more than 2 alleles for a Single gene Ex (ABO Blood)

• Another term used to describe 'heterozygous'

• Determining the potential offspring by Crossing 2 traits

• When 2 alleles are equally dominant & both Show in Heterozygote

What is the definition of 'Codominance'?

• When dominant and recessive alleles blend in a Heterozygote

• When the genotype has one dominant and one recessive allele

• When 2 alleles are equally dominant & both show in Heterozygote

• Multiple sets of genes determine the outcome of One trait

What does 'Heterozygous' mean?

• Having two of the same exact alleles ex. EE

• When the genotype has one dominant and one recessive allele

• A version of a gene (represented with 1 letter)

• Another term used to describe homozygous

What is 'Polygenic inheritance'?

• Determining the potential offspring by Crossing 2 traits

• The physical expression of genes

• Multiple sets of genes determine the outcome of One trait

• When dominant and recessive alleles blend in a Heterozygote
