Suppose you have monohybrid pea plants in your garden and find that they produce round seeds to wrinkled seeds in the ratio of 3: 1 if the alleles are designated r and r, respectively, what are the probable genotypes of the wrinkled seeds produced by your plants

The answer is rr. In a monohybrid cross, the phenotypic ratio is 3:1 for dominant trait to recessive trait. Since the ration is 3:1 for round seeds to wrinkled seeds, we can conclude that round seed is the dominant trait. Let R be a dominant allele for round seed and r be a recessive allele for wrinkled seed. The genotypes will be: RR (dominant homozygote with round seeds), Rr (heterozygote with round seeds), and rr (recessive homozygote with wrinkled seeds. Thus, only genotype rr is the genotype of the wrinkled seeds.

The answer is joseph is observing the colour of the reaction mixture to see whether proteins are present in the given solution.
