Heredity
Which of the following is an example of Non-Mendelian inheritance?
Simple dominant and recessive traits
Traits following a 3:1 phenotypic ratio
Sex-linked traits
Traits determined by one gene
Mendelian inheritance typically involves how many alleles for a particular trait, while Non-Mendelian inheritance can involve how many?
Two, always less than two
Three, only two
Two, multiple
One, two
How do multiple alleles differ from simple Mendelian inheritance?
Multiple alleles involve only two phenotypes, while Mendelian inheritance involves more.
Multiple alleles involve more than two alleles for a trait, while Mendelian inheritance typically involves two.
Multiple alleles always result in a 3:1 phenotypic ratio, while Mendelian inheritance does not.
Multiple alleles are always dominant, while Mendelian inheritance involves dominant and recessive alleles.
In the ABO blood group system, which allele(s) is/are recessive?
IA
IB
i
Both IA and IB
How do multiple alleles increase the variety of phenotypes in a population?
By decreasing the number of possible genotypes.
By providing more combinations of alleles, leading to more diverse traits.
By limiting the expression of certain genes.
By making all alleles dominant.
In the ABO blood group system, what is the relationship between the IA and IB alleles?
IA is dominant to IB
IB is dominant to IA
They are codominant
They are both recessive
How does Non-Mendelian inheritance differ from Mendelian inheritance in terms of phenotypic ratios?
Non-Mendelian inheritance always results in a 3:1 phenotypic ratio.
Non-Mendelian inheritance often leads to more varied phenotypic ratios due to factors like multiple alleles.
Non-Mendelian inheritance results in the same phenotypic ratios as Mendelian inheritance.
Non-Mendelian inheritance only affects genotypic ratios, not phenotypic ratios.

In a population of rabbits, fur color is determined by multiple alleles. If there are four different fur colors, what does this indicate about the number of alleles present for fur color?
There are only two alleles present.
There are exactly four alleles present.
There are at least three alleles present.
There is only one allele present.
A woman with type A blood has a child with type O blood. Her husband is type B. What are the possible genotypes of the mother?
IAIA or IAi
IBIB or IBi
ii
IAIB
Which of the following is a characteristic of non-Mendelian inheritance?
Traits are determined by a single gene with two alleles.
Phenotypic ratios always follow a 3:1 pattern.
Inheritance patterns are more complex than simple dominant and recessive relationships.
Each gene has only one possible version.
