You and 99 friends are on a three hour boat tour when the weather started getting rough and you were stranded on a desert island. Three of you friends are carriers of the gene for albinism, but no one on the trip is albino. What percentage of the island’s population in the next generation do you expect to be albino? Carriers of this gene?  

Assume that the albinism gene above also allowed individuals who are carriers to avoid a deadly illness caused by consuming the seaweed that grows on the island – one of the few food sources available. Do you predict that will impact the frequency of that allele in the gene pool?Assume that the albinism gene above also allowed individuals who are carriers to avoid a deadly illness caused by consuming the seaweed that grows on the island – one of the few food sources available.

How are vaccines made? - Why do they take so long to make? - Why can't you just walk into Walgreens and buy a vaccine for Covid-19 yet?

Albinism is a rare autosomal recessive trait in which there is a complete absence of melanin pigment in the skin, eyes, and hair. A normally pigmented woman whose parents are normal has a brother who is albino. She marries a normally pigmented man whose grandfather was albino. What is the probability their first child will be albino?

I would like to see the problem worked out. Dont understand why it is 1/12. Thank you in advance

This topic's discussion focuses on the basic processes of how cells are able to do what they do--the central dogma of life. In order for cells to function effectively, they need to make proteins, which, as we learned way back in Topic 2 (Ch. 4) are responsible for doing all of the work inside of (and for) the cell (enzymes) and provide the necessary structure for cells to function (cytoskeleton, some signaling molecules, binding proteins, receptors, transporters, etc.). Each cell has all of the information the organism needs to make these proteins (in the form of genes on chromosomes--the DNA), although it only makes the proteins that it needs when it needs them. The processes of reading the DNA to make the RNA and reading the RNA to make the proteins are together known as the central dogma (and sometimes DNA replication is included since it is also required for living organisms to make new cells). Your discussion postings this week should focus on some aspect of the central dogma and provide more detail for your fellow classmates. For example, one of the parts and how it is controlled, where it occurs, what can go wrong, or how they're connected. Along with the responses, this discussion should give you a much better understanding of how life actually works! Do not use other solutions. I need originality responses as well as IN TEXT CITATIONS AND A WORKS CITED REFERENCE. Please use 2 outside references.Thank you

Prepare and present on a specific answer to this very broad question: How does biology shape our lives and society?

The end of the chapter talks about DNA repair, and the discussion for this topic will follow up on this idea further. You should do further research on some aspect of DNA repair. For example: how it works the different types why it's important how it can go wrong what results when it goes wrong its importance to cancer.. Do not use other solutions. I need originality responses as well as IN TEXT CITATIONS AND A WORKS CITED REFERENCE. Please use 2 outside references.Thank you
