Define Genotypes and Phenotypes Quick Check 1 of 41 of 4 Items Question In pea plants, the allele for purple flowers, P, is dominant over the allele for white flowers, p. Which conclusion about phenotype and genotype is possible?(1 point) Responses If a plant has purple flowers, then its genotype must be Pp. If a plant has purple flowers, then its genotype must be Pp . If a plant has purple flowers, then its genotype must be PP. If a plant has purple flowers, then its genotype must be PP . If a plant has white flowers, then its genotype must be Pp. If a plant has white flowers, then its genotype must be Pp . If a plant has white flowers, then its genotype must be pp.
If a plant has purple flowers, then its genotype must be either PP or Pp.
only pick one
If a plant has purple flowers, then its genotype must be Pp.
If a plant has purple flowers, then its genotype must be Pp.
To answer this question, we need to understand the concepts of genotypes and phenotypes. Let me explain:
1. Genotype: This refers to the actual genetic makeup or combination of alleles (forms of a gene) that an individual possesses. In this case, the alleles for flower color in pea plants are P (dominant allele for purple flowers) and p (recessive allele for white flowers).
2. Phenotype: This refers to the observable physical traits or characteristics of an individual, which are determined by the interaction between the genotype and the environment. In this case, the phenotypes are purple flowers (determined by the dominant P allele) and white flowers (determined by the recessive p allele).
Now let's analyze the given options and find the correct conclusion:
- If a plant has purple flowers, then its genotype must be Pp.
- If a plant has purple flowers, then its genotype must be PP.
- If a plant has white flowers, then its genotype must be Pp.
- If a plant has white flowers, then its genotype must be pp.
Based on the information provided, we know that the allele for purple flowers (P) is dominant over the allele for white flowers (p). This means that if a plant has purple flowers, it could have two possibilities for its genotype: either PP (homozygous dominant) or Pp (heterozygous dominant). Therefore, the correct conclusion is:
If a plant has purple flowers, then its genotype must be Pp.
So, the correct option is: "If a plant has purple flowers, then its genotype must be Pp."
