The genotype of plants with the recessive phenotype of wrinkled seeds is always homozygous. However, when an individual plant expresses the dominant phenotype of round seeds, it can have either the genotype RR or Rr. How could you test whether the dominant individual is a true breeder (RR)?

genotypes and phenotypes in dominant and recessive ... Mendel's parental pea plants always bred true because both produced ... The recessive trait will only be expressed by offspring that have two copies of ... You do a test cross between a pea plant with wrinkled peas (genotype rr)

the types of mutations include: missense mutation: this type of mutation is a change in one dna base pair that results in the substitution of one amino acid for another in the protein made by a gene. nonsense mutation: a nonsense mutation is also a change in one dna base pair.

explanation:

the correct answer is option b

behavioral response need communication and thus co-ordination at several levels such as interaction among cells, organ system and the entire organism.

behavioral response produces both internal and environmental stimulus.
