There are multiple alleles for the ABO blood group. Why are only two of these alleles present in any one individual?
Each parent contributes only one allele for the ABO blood group to the offspring.
There are not enough nucleotides in a red blood cell to produce a third allele.
Each allele in the ABO group must be dominant or recessive
Blood group alleles are not segregated during meiosis.
Which term(s) best describes the inheritance of human blood types?
incomplete dominance and multiple alleles
codominance and epistasis
codominance and multiple alleles
incomplete dominance and codominance
Human blood type is determined by multiple alleles (A, B, and O). Which ratio would result from a cross between a man with Type AB blood and a woman with Type O blood?
A. 50% Type A, 50% Type O
B. 75% Type A, 25% Type B
C. 50% Type A, 50% Type B
D. 100% Type O
A geneticist studying the inheritance of flowers performed a series of crosses. The results from the crosses are listed in the data table above. Based off the data above, which mode of inheritance is flower color?
A. codominance
B. incomplete dominance
C. complete dominance
D. polygenic
Skin colour, height, hair colour, and eye colour are human traits that show high variations--these traits demonstrate
incomplete dominance
codominance
multiple alleles
polygenic inheritance
A trait is varies in rabbits more than classic Mendelian dominance, or non-Mendel dominances. This trait is controled by ONE gene having four alleles in the population, but only two are inherited. This demonstrates the pattern of inheritance with
gene variations
codominance
polygenic epistasis
multiple alleles
A circumstance where the expression of a trait is affected by the expression of one or more independently inherited genes--it either obliterates the trait or modifies it.
codominance
epistasis

enzyme
Human height is controlled by many genes, at least 5. Another gene, D, controls achondroplasia dwarfism which is dominant if heterozygous (DD is a lethality). This gene is ___ to height.
epistatic
codominant
multiple allelic
incompletely dominant
Corn has high variability. Kernel colour appears to be consistent with:
incomplete dominance
polygenics
epistasis
Mendelian dominance
View the eye. After viewing the eye, assess the type of inheritance pattern that is noted (and from your lab)
polygenic
co-dominance
multiple allele
two or more patterns may be occurring
