Can a human male be a carrier of red-green color blindness?
Yes, males can be carriers of red-green color blindness, as color blindness is autosomal dominant
No, males cannot be the carriers of red-green color blindness, as color blindness is X-linked
No, males cannot be the carriers of red-green color blindness, as color blindness is Y-linked
Yes, males can be carriers of red-green color blindness, as color blindness is autosomal recessive
What is an example of a codominant trait in the human body?
Hair color
Skin Color
Blood Type
Color Blindess

Mom: HH, Dad: HH
In Snowmen, three buttons (B) is dominant to two buttons (b), and a carrot nose (N) is dominant to a coal nose (n). What would be the genotype of a snowman that was homozygous recessive for button number and heterozygous for nose type?
BBNn
bbNN
bbNn
BbNn
What is codominance?
Both alleles are partially expressed
Both alleles are recessive
Both alleles are equally strong and visible
Neither allele is expressed
What is incomplete dominance?
One allele is expressed over the other in a heterozygote
When both alleles are expressed in a heterozygote
A blend of the parental traits; neither is dominant
When your parents can't agree on what's for dinner
What is a gene loci
Heterozygous carrier of a recessive disease
Having two copies of the same dominant allele
Specific positions of genes on a chromosome
Having two copies of the same recessive allele

Amylase is an enzyme found in saliva. It helps breakdown starch found in foods such as crackers, cereals, potatoes, etc. into glucose that can be absorbed by the body. In this experiment Amylase was mixed with an unknown chemical B. Which of the following best matches the identity of chemical B?
Chemical B is additional starch
Chemical B is acidic
Chemical B is glucose
Chemical B is additional Amylase
Monozygotic twins can look different to one another because:
they have different genetic material from the mother but the same genetic material from the father.
they have different genetic material from the father but the same genetic material from the mother.
the environment is determinative of phenotype.
a mutation has occurred in one twin during embryonic development.
