Challenge Problem: Incomplete dominance is seen in snapdragons. The allele that causes red flowers (R) is not completely dominant over the allele that causes white flowers (W). When a plant is heterozygous for the trait of flower color (RW), pink flowers result. Cross two pink snapdragons, and provide the genotype and phenotype of all offspring.

i think a) betsy can donate only blood to mark is correct because, mark and betsy have the same blood type. whereas nobody else has b+ blood so betsy can't donate to them.

genetic variation will increase because of a new habitat and food source.

explanation:

a scenario where a cell may be needed to perform a form of endocytosis is when transporting large molecules. a scenario where a cell may be needed to perform a form of exocytosis is when releasing the large molecule from the cell.
