Quick comprehension check
“A pea plant with a genotype of Rr (where R is the dominant allele for round seeds and r is the recessive allele for wrinkled seeds) is crossed with another pea plant that has a genotype of Rr. Use a Punnett square to predict the genotypes of the offspring and state the expected phenotypes. A fruit fly with a genotype of Bb (where B is the dominant allele for black body color and b is the recessive allele for brown body color) is crossed with a fruit fly that has a genotype of bb. Use a Punnett square to predict the genotypes of the offspring and state the expected phenotypes.”
