Question

if these two plants were to cross, what would the offspring look like? an offspring gets 1 allele from each parent for each trait. since there are two traits for each parent, the offspring will be represented by a four-letter genotype. fill in the genotype of the f1 offspring. legend y = yellow pods y = green pods r = round seeds r = wrinkled seeds what will be the genotype and phenotype of the offspring of these two plants? genotype: dropdown with options: yyrr, yyrr, yyrr, yyrr, yyrr, yyrr, yyrr phenotype: blank

Explanation:

To solve this, we assume the parents are homozygous (since it's a typical dihybrid cross setup, though the parent genotypes aren't fully shown, but the F1 is usually heterozygous for both traits in classic Mendelian examples).

Step 1: Determine Alleles for Each Trait

For pod color: If one parent is \( YY \) (yellow) and the other \( yy \) (green), the offspring gets one allele from each, so \( Yy \).
For seed shape: If one parent is \( RR \) (round) and the other \( rr \) (wrinkled), the offspring gets one allele from each, so \( Rr \).

Step 2: Combine Traits for Genotype

The F1 offspring’s genotype combines the two traits: \( YyRr \) (since it inherits \( Y \) or \( y \) for pods and \( R \) or \( r \) for seeds, and in a typical cross, heterozygous for both).

Step 3: Determine Phenotype

• Pod color: \( Y \) is dominant (yellow), so \( Yy \) gives yellow pods.
• Seed shape: \( R \) is dominant (round), so \( Rr \) gives round seeds.

Thus, the phenotype is yellow pods and round seeds.

Answer:

Genotype: \( YyRr \)
Phenotype: Yellow pods and round seeds
