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

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

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

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

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.

D  is expressed in the phenotype alongside a dominant allele.

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

B  DNA was the molecule carrying the genetic code.

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

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

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