B  FALSE

A  The dominant 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  The recessive 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.

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

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

C  have their own unique phenotypes and are geographically isolated from one another, but are 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.

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

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