The correct Answer is:
To determine the genotype for a dwarf, wrinkled, and yellow-seeded pea plant, we need to analyze the genetic traits provided: 1. **Identify the traits and their corresponding alleles**: - Round seeds (W) are dominant over wrinkled seeds (w). - Yellow seeds (Y) are dominant over green seeds (y). - Tall plants (T) are dominant over dwarf plants (t). 2. **Determine the phenotype we are looking for**: - Dwarf: This means the plant must have the recessive allele for height, which is represented by "tt". - Wrinkled seeds: This means the plant must have the recessive allele for seed shape, represented by "ww". - Yellow seeds: Since yellow is dominant, the plant can either be homozygous dominant (YY) or heterozygous (Yy). However, since we are not given any indication of the green phenotype, we will assume the plant is at least heterozygous for yellow, which is "Yy". 3. **Combine the alleles to form the genotype**: - For dwarf: tt - For wrinkled: ww - For yellow: Yy 4. **Construct the complete genotype**: - The complete genotype for a dwarf, wrinkled, and yellow-seeded plant would be "ttwwYy". Thus, the genotype for a dwarf, wrinkled, and yellow-seeded plant is **ttwwYy**.
