Description : The process by which organisms with different evolutionary history evolve similar phenotypic adaptations in response to a common environmental challen
Last Answer : The process by which organisms with different evolutionary history evolve similar phenotypic ... Convergent evolution D. Non-random evolution
Description : How does incomplete dominance differ from complete dominance in it's phenotypic expression?
Last Answer : In complete dominance, only one allele in the genotype is seen in the phenotype. In codominance, both alleles in the genotype are seen in the phenotype. In incomplete dominance, a mixture of the alleles in the genotype is seen in the phenotype.
