According to the video “The Biology of Skin Color”, why is it that the allele coding for darker skin did not evolve to protect us from skin cancer? A. Because skin cancer isn't harmful B. Darker skin did develop to protect us from skin cancer C. Because skin cancer usually develops after an individual's reproductive years, so it doesn't affect the ability for someone to pass on their genes D. Because skin cancer usually develops before an individual's reproductive years, so it doesn't affect the ability for someone to pass on their genes

When Gregor Mendel first proposed his theories on genetics, they were not recognized. This was because: A. Charles Darwin didn't agree with Gregor Mendel's theories. B. The current theory was that traits from parents blended together in their offspring. C. Gregor Mendel proposed that individuals could change their physical traits during their lifetime and pass those new traits on to their offspring. D. Scientists believed there were 5 nucleotide bases, not 4 nucleotide bases.
in a summary 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.
