Question

select the phenotype of the following genotypes
rr dropdown with round seed, wrinkled seed
rr
yy
yy
checkboxes y, y
next

Explanation:

To solve this, we analyze each genotype:

For \( Rr \):

In Mendelian genetics, \( R \) (round) is typically dominant over \( r \) (wrinkled). A heterozygous genotype (\( Rr \)) expresses the dominant phenotype. So \( Rr \) corresponds to Round Seed.

For \( rr \):

A homozygous recessive genotype (\( rr \)) expresses the recessive phenotype. Since \( r \) is for wrinkled, \( rr \) corresponds to Wrinkled Seed.

For \( YY \):

\( Y \) (e.g., for yellow seed color, if \( Y \) is dominant) in a homozygous dominant genotype (\( YY \)) expresses the dominant phenotype. Assuming \( Y \) is dominant (e.g., yellow over green), \( YY \) would show the dominant trait (e.g., Yellow Seed—though the exact trait depends on context, but the pattern is dominant phenotype for \( YY \)).

For \( yy \):

A homozygous recessive genotype (\( yy \)) expresses the recessive phenotype. If \( Y \) is dominant (e.g., yellow), \( yy \) would show the recessive trait (e.g., Green Seed—again, context-dependent, but follows recessive expression for \( yy \)).

Final Selections:

• \( Rr \): Round Seed
• \( rr \): Wrinkled Seed
• \( YY \): Dominant phenotype (e.g., Yellow Seed, based on typical Mendelian patterns)
• \( yy \): Recessive phenotype (e.g., Green Seed, based on typical Mendelian patterns)

(Note: The exact trait name for \( Y/y \) depends on the specific gene (e.g., seed color, flower color), but the principle of dominant/recessive expression holds.)
