A  FALSE

B  TRUE

A  When both alleles are present none of them will be passed down to the next generation

B  The recessive allele is more likely to be passed down.

C  The dominant allele is more likely to be passed down.

D  Both alleles have an equal probability of being passed down to the offspring.

A  No since all traits are only controlled by one gene with two alleles.

B  None of the other responses are satisfactory answers.

C  No since different genes will exert varying degrees of influence on the trait

A  A theory has been less thoroughly tested than a hypothesis.

B  A theory is an explanation that has been carefully examined and tested.

D  A theory is an explanation based upon controversial facts.

A  have their own unique phenotypes and are geographically isolated from one another, but are capable of successful interbreeding.

B  are geographically isolated from one another, look alike, but are not capable of successful interbreeding.

C  may share the same geographic area but are so phenotypically different that they never attempt to reproduce.

D  have their own unique phenotypes and are geographically isolated from one another, but if they do happen to encounter one another, they are still capable of interbreeding although their offspring are infertile.

A  FALSE

C  is expressed in the phenotype alongside a dominant allele.

D  can never be expressed in the phenotype.

A  peas were a poor choice for understanding basic hereditary principles.

B  traits inherited from each parent blended together in the offspring.

C  DNA was the molecule carrying the genetic code.

D  traits are passed on from parent to offspring as discrete units.

A  Being the same makes everybody stronger since they are pure blooded and as a result are more likely to survive.

B  Diseases typically attack individuals and not populations.

C  A disease that kills one individual is likely to kill everybody else.
