Dominant vs. Recessive Alleles

Prompt: After attending the lecture on Mendelian inheritance your study group is having great difficulty understanding the mechanism of dominance. They seem to think that the dominant allele masks or overrides the recessive allele in some way, but you know that it’s all about the products that the alleles are or are not expressing. Prepare an essay that you can present to your study group to help them understand the concept of dominance. Use your understanding of molecular biology to explain that recessive alleles are expressed through transcription and translation, and that they may have functional gene products. Describe how the interaction of the products produced by each allele results in what we see as dominant or recessive traits. Your summary should be typed in Times New Roman 12-pt font and be one-and-a-half-spaced with 1” margins.
