Question

which of the following is the accurate representation of the genotype (letters) for a pea plant that is heterozygous purple? (purple is the dominant color and white is the recessive color)
○ pp
○ pp
○ pp
○ pw

Explanation:

To determine the heterozygous genotype for purple (dominant) and white (recessive) in pea plants:

• Heterozygous means having two different alleles (one dominant, one recessive).
• Dominant alleles are typically represented by uppercase letters (e.g., \( P \) for purple), and recessive by lowercase (e.g., \( p \) for white).
• \( Pp \) has one dominant (\( P \)) and one recessive (\( p \)) allele (heterozygous).
• \( PP \) is homozygous dominant, \( pp \) is homozygous recessive, and \( PW \) uses an incorrect allele symbol (white should be \( p \), not \( W \)).

Answer:

A. Pp
