A student argues that being separated geographically is the only way for speciation to occur. Why is he wrong? *Speciation does not usually rely on geographic isolation.
*Speciation can occur from biological forces as well.
*Speciation can occur from variation as well.
*Speciation does not result from adaptive radiation.

I have all the answers for the quiz (#4 is A)!

In sweet pea, gene c is responsible for color production and gene p is responsible for the purple color pigment. both of them are located on two different loci on different chromosomes. the flowers will be purple only when the plant has the genotypes as c_p_. no color will be produced with genotypes: ccpp, ccpp, ccpp, ccpp. thus, gene c controls the expression of gene p. what pattern of inheritance is exhibited here? a. pleiotropy b. epistasis c. multiple alleles
