Question

question 17
if you see a pea plant that has white flowers, what can you determine about its genotype?
its genotype is likely aa.
its genotype is surely aa.
its genotype is likely aa.
its genotype is surely aa.

Explanation:

Step1: Understand dominant and recessive traits

In pea plants, assume purple is dominant (A) and white is recessive (a).

Step2: Analyze genotypes and phenotypes

• AA: Dominant (purple)
• Aa: Dominant (purple) (because A is dominant)
• aa: Recessive (white) (only when both alleles are recessive)

Since the plant has white flowers (recessive phenotype), it must have two recessive alleles. So its genotype is surely aa.

Answer:

Its genotype is surely aa.
