- Gregor Mendel discovered the basis of heredity with his sweet pea plant experiments. In his studies, he determined that certain traits, such as pod color and pea shape, express complete dominance. Trait Dominant Recessive Pod color Yellow Green Pea shape Round Wrinkled A cross occurs between a plant with heterozygous yellow pods and wrinkled peas and a plant with green pods and heterozygous round peas. What is the probability that the offspring will exhibit recessive genes for both traits? a) 1/2 b) 1/4 c) 1/8 d) 1/16arrow_forwardExplain the term of co-dominance?arrow_forwardAre both incomplete dominance and codominance illustrated with two capital letters?arrow_forward

What is the probability (%) that the offspring will have red flowers?arrow_forwardIf body-color B is dominant to green body color b what would the genotype be for a heterozygous individual be? Using the blue B and a green b body color from above create a Punit square that represents the offspring of two heterozygous parents? what is the probability that they will have a child with a green body-color If the child is green what is its genotype? Cross a green parent with a homozygous blue parent. What color will their kids be?arrow_forwardCompare and contrast the following pairs, include examples: 1. Genotype vs. Phenotype 2.
