Which statement best describes the relationship between an allele and a gene?
An allele is a segment of a DNA molecule that controls replication of a gene
An allele is a variation of a gene that can be expressed as a phenotype
An allele is the primary protein made by a gene found in a developing embryo
An allele is the part of a gene that attaches to messenger RNA molecules

Punnet squares can be used to predict the probability of:
having an inherited disease or a genetically determined physical trait
both of the above
being exposed to a contagious disease and contracting it
Punnet squares are created by geneticist to determine the probability of different offspring genotypes.  In the one shown below, what letter s belong in the lower right box?

aa
a
Aa
AA
If two people who are both carriers (heterozygous) for a genetically inherited fatal recessive disease decide to become parents, what will be the odds that their children will also be carriers?
1 out of 4
2 out of 4
3 out of 4
4 out of 4
When Mendel crossed a purple flowered pea plant with a white flowered pea plant, the offspring always had purple flowers. When he crossed the offspring with each other, the second-generation offspring had some white flower plants. What conclusions can can be drawn from this observation?
The first generation will have a 3:1 purple to white ratio
The offspring from the 2nd generation are all heterozygous
The offspring from the first generation are heterozygous
The 2nd generation will be in a 1:1 purple to white ratio
In guinea pigs black fur (B) is dominant over brown fur (b).  If you breed guinea pigs with the genotype Bb and Bb, what is the likelihood of breeding offspring that has black fur?

One of the parents of a child has phenylketonuria (PKU), which is caused by recessive alleles. The other parent does not have the PKU alleles (not a carrier either). What is the chance that the couple will have a child with phenylketonuria?
