Principle of segregation12/29/2023 Wrinkled seed shape (rr) and green seed color (yy) are recessive. In this cross, the traits for round seed shape (RR) and yellow seed color (YY) are dominant. For example, a plant that had round seeds and yellow seed color was cross-pollinated with a plant that had wrinkled seeds and green seed color. Mendel performed dihybrid crosses in plants that were true-breeding for two traits. Mendel's Independent Assortment Experiment Heterozygous alleles exhibit complete dominance as one allele is dominant and the other recessive.These alleles separate during meiosis, leaving each gamete with one allele for a single trait.Organisms inherit two alleles (one from each parent) during sexual reproduction. ![]()
