What is the blood type of a person with the alleles iA and iO? |
The person will have type A blood because A is dominant to O. (normal dominance) |
|
|
The crossing of a white and a red flower produces a pink flower. What type of dominance is this? |
incomplete dominance |
|
|
The crossing of a white and red flower produces a red and white spotted flower. What type of dominance is this? |
codominance |
|
|
A person has the following alleles for the gene for blood type: iA and iB. What is this person's blood type? (phenotype) and what type of dominance is this? |
The person has AB blood. This is an example of codominance. |
|
Is the trait recessive or dominant? Affected individuals are solid. |
recessive |
|
What are the genotypes of the first generation parents? |
heterozygous (Aa and Aa) |
|
|
If the allele for red flowers is R and the allele for white flowers are W and the trait shows incomplete dominance, what is the genotype of a pink flower? |
RW |
|
|
What would the punnett square look like for a cross between two pink flowered plants if the color is the result of incomplete dominance? |
1 red, 2 pink and 1 white |
|
|
Can a person with AB blood who has children with a person heterozygous for type A blood have a child with type O blood? Why or why not? |
No. Type O blood is recessive and requires two O alleles. The type AB person does not carry the O allele. |
