Answer it

Distinguish between genotype and phenotype and give examples that relate this distinction to dominant and recessive alleles and to the molecular mechanisms of gene action. Explain examples of the molecular basis of dominant traits (often gain of function) and recessive traits (often loss of function). Recognize that dominance does not equal prevalence. Using the terms alleles and genes describe how genetic variation is generated by meiotic independent assortment and by recombination during crossing over. Be able to label and 1. Outline the difference between the genotype and the phenotype. Which one is strictly inherited from the parents? 2. Explain how the diploid genome structure contributes to protein diversity within a cell. How many different versions of a single protein can be found in a cell? 3. Assign a description and name the type of dominance observed the images. Heterozygote has an intermediate phenotype between either homozygote. Heterozygotes resemble homozygous dominant. Heterozygote expresses both homozygous phenotypes equally
