Probability of Offspring Having Wrinkled, Green Seeds from Cross of SsYy and SSYY Plants: 0%

To determine the probability that the offspring of the plants will have wrinkled, green seeds, we need to analyze the given genotypes of the parents and predict the genotypes of the offspring. Let's break it down step-by-step: 1. **Determine the alleles contributed by each parent:** - Parent 1: SsYy (heterozygous for both traits) - Parent 2: SSYY (homozygous dominant for both traits) 2. **Identify the possible gametes from each parent:** - Parent 1 (SsYy) can produce four different combinations of alleles: SY, Sy, sY, sy. - Parent 2 (SSYY) can only produce one type of gamete: SY. 3. **Determine the genotypes of the offspring by combining the gametes:** - The possible combinations are: - SY (from Parent 1) with SY (from Parent 2) = SSYY (homozygous dominant for both traits) - Sy (from Parent 1) with SY (from Parent 2) = SSYy (heterozygous dominant for the seed coat and homozygous dominant for the seed color) - sY (from Parent 1) with SY (from Parent 2) = SsYY (heterozygous for the seed coat and homozygous dominant for the seed color) - sy (from Parent 1) with SY (from Parent 2) = SsYy (heterozygous for both traits) 4. **Determine the phenotypes of the offspring:** - SSYY: Smooth, yellow seeds - SSYy: Smooth, yellow seeds - SsYY: Smooth, yellow seeds - SsYy: Smooth, yellow seeds All possible offspring have smooth, yellow seeds because they all have at least one dominant allele for each trait (smooth seed coat (S) and yellow seed coat (Y)). 5. **Determine the probability of getting wrinkled, green seeds:** - Wrinkled seeds require the genotype ss (recessive for seed coat). - Green seeds require the genotype yy (recessive for seed color). As none of the gamete combinations produce an offspring with both recessive alleles for seed coat and seed color (ssyy), it is not possible for the offspring to have wrinkled, green seeds. Therefore, the probability of the offspring having wrinkled, green seeds is: **A. 0% (zero percent)**
