Question

1. for each genotype, list the phenotype.

pp
rr
rr
gg
rr
gg

Explanation:

To solve this, we assume standard Mendelian genetics where dominant alleles determine the phenotype (uppercase letters) and recessive alleles are expressed only in homozygous form (lowercase). Let's define the traits (common examples: \( P/p \) for flower color, \( Y/y \) for seed color, \( F/f \) for a trait like fur, \( G/g \) for another trait):

Step 1: Analyze \( pp \)

• \( p \) is recessive. Homozygous recessive (\( pp \)) expresses the recessive phenotype. If \( P \) = purple (dominant), \( pp \) = white? Wait, maybe the original context has \( P \) as purple (dominant), but the handwritten answer says "Purple"—maybe a typo. Wait, no—if \( P \) is dominant (purple), \( pp \) would be recessive (e.g., white), but the handwritten answer says "Purple". Maybe the trait is \( p \) = purple (recessive)? Or maybe the problem defines \( p \) as purple. Assuming the problem’s context (e.g., \( P \) = purple is dominant, but \( pp \) here is a mistake? Or maybe the trait is different. Let's proceed with common examples:

Step 2: Analyze \( Yy \) (wait, the second is \( Yy \)? Wait, the image shows \( Yy \)? Wait, the user’s image: first row \( pp \) (handwritten "Purple"), \( Yy \) (handwritten "Yellow")? Wait, no—second column first row: \( Yy \)? Wait, the image is blurry, but let's use standard genetics:

• \( pp \): If \( P \) = purple (dominant), \( pp \) is recessive (e.g., white). But handwritten says "Purple"—maybe the trait is \( p \) = purple (recessive is white, but \( pp \) is purple? No, dominant is expressed in heterozygous. Wait, maybe the problem has \( P \) = white (dominant) and \( p \) = purple (recessive). Then \( pp \) = purple.
• \( Yy \): If \( Y \) = yellow (dominant), \( Yy \) (heterozygous) = yellow.
• \( Ff \): If \( F \) = a dominant trait (e.g., black fur), \( Ff \) = black.
• \( Gg \): If \( G \) = a dominant trait (e.g., green), \( Gg \) = green.
• \( ff \): Homozygous recessive, expresses recessive phenotype (e.g., white fur).
• \( gg \): Homozygous recessive, expresses recessive phenotype (e.g., yellow).

But since the problem is about listing phenotypes from genotypes, we use the principle:

• Homozygous dominant (e.g., \( PP \)) or heterozygous (e.g., \( Pp \)) → dominant phenotype.
• Homozygous recessive (e.g., \( pp \)) → recessive phenotype.

Assuming the problem’s traits (from handwritten answers):

• \( pp \): Purple (maybe \( p \) is dominant here, or the problem defines \( p \) = purple).
• \( Yy \): Yellow (since \( Y \) = yellow, heterozygous expresses dominant).
• \( Ff \): Dominant phenotype (e.g., if \( F \) = black, then black).
• \( Gg \): Dominant phenotype (e.g., green).
• \( ff \): Recessive phenotype (e.g., white).
• \( gg \): Recessive phenotype (e.g., yellow).

Final Answers (matching typical Mendelian genetics with the problem’s context):

• \( pp \): Purple (if \( p \) is recessive but the problem defines it as purple)
• \( Yy \): Yellow (dominant phenotype)
• \( Ff \): Dominant phenotype (e.g., Black)
• \( Gg \): Dominant phenotype (e.g., Green)
• \( ff \): Recessive phenotype (e.g., White)
• \( gg \): Recessive phenotype (e.g., Yellow)

(Note: The exact phenotypes depend on the problem’s trait definitions, but the key is applying dominant/recessive inheritance.)

Answer:

(based on standard genetics and the handwritten hints):

• \( pp \): Purple (assuming \( p \) = purple, recessive)
• \( Yy \): Yellow (dominant)
• \( Ff \): [Dominant trait, e.g., Black]
• \( Gg \): [Dominant trait, e.g., Green]
• \( ff \): [Recessive trait, e.g., White]
• \( gg \): [Recessive trait, e.g., Yellow]

(If we strictly follow the handwritten answers: \( pp \) = Purple, \( Yy \) = Yellow, \( Ff \) = [Dominant], \( Gg \) = [Dominant], \( ff \) = [Recessive], \( gg \) = [Recessive].)
