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

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

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

C  None of the other responses are satisfactory answers.

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

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

C  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.

B  DNA was the molecule carrying the genetic code.

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

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

A  Natural selection does not deal with diseases and as a result this scenario is not possible.
