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_forward

A complete dominance and co - dominance B. genotype and phenotypearrow_forwardIf an allele is dominant then only one copy is sufficient for it to be visible in the phenotype. True or false?arrow_forwardDescribe the diference between incomplete dominance and codominance.arrow_forward
- Mendel's concept of dominance states that in a genotype where two different alleles of a locus are present, only the trait encoded by the dominant allele is observed. Give a molecular explanation for dominance, i.e. explain intracellular molecular events that can result in what we observe as dominance on a phenotypic level. Use the gene that encodes seed shape in peas as an example, where roun(R) is dominant over wrinkled(r), to explain how RR and Rr plants can have the same phenotype.arrow_forwardIn wobble bats coat color is determined by a single gene.
