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

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

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

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

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  peas were a poor choice for understanding basic hereditary principles.

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