Question

dominant alleles suppress the expression of recessive alleles.
label the offspring of this cross with their correct phenotype (appearence).
combination 1 image: two circles with p, label pp
combination 2 image: circles with p and p, label pp
combination 3 image: circles with p and p, label pp
combination 4 image: two circles with p, label pp

Explanation:

Step1: Recall Dominant/Recessive Rules

Dominant allele (P) masks recessive (p). Genotypes with at least one P (PP, Pp, pP) show dominant phenotype; pp shows recessive.

Step2: Analyze Each Combination

• Combination 1 (pp): Recessive, so phenotype = White.
• Combination 2 (Pp): Has dominant P, so phenotype = Purple.
• Combination 3 (pP): Has dominant P, so phenotype = Purple.
• Combination 4 (pp): Recessive, so phenotype = White.

Answer:

Combination 1: White
Combination 2: Purple
Combination 3: Purple
Combination 4: White
