If the two alleles for a particular gene are identical the gene pair is:
- Multiple Choice
Mendel's pea plants can have yellow peas or green peas. Mendel found the yellow pea color allele to be dominant over the green pea color allele. What does this mean?
- Multiple ChoiceIn a certain plant, the alleles A, B, and C are completely dominant to the alleles a, b, and c. A plant with the genotype AABbcc will have the same phenotype as a plant with the genotype __________.
- Open QuestionWhat is the relationship between genotype and phenotype?
- Open QuestionComplete this concept map to help you review some key concepts of genetics. a. b. c. d. e. f.
- Open QuestionWhether an allele is dominant or recessive depends ona. how common the allele is, relative to other alleles.b. whether it is inherited from the mother or the father.c. whether it or another allele determines the phenotype when both are present.d. whether or not it is linked to other genes.
- Open QuestionWhy is the pea wrinkle-seed allele a recessive allele?a. It 'recedes' in the F2 generation when homozygous parents are crossed.b. The trait associated with the allele is not exhibited in heterozygotes.c. Individuals with the allele have lower fitness than that of individuals with the dominant allele.d. The allele is less common than the dominant allele. (The wrinkled allele is a rare mutant.)
