Utilizing Markov Chains To Estimate Allele Progression Through Generations, Ronit Gandhi Jan 2023

Utilizing Markov Chains To Estimate Allele Progression Through Generations, Ronit Gandhi

Honors Theses

All populations display patterns in allele frequencies over time. Some alleles cease to exist, while some grow to become the norm. These frequencies can shift or stay constant based on the conditions the population lives in. If in Hardy-Weinberg equilibrium, the allele frequencies stay constant. Most populations, however, have bias from environmental factors, sexual preferences, other organisms, etc. We propose a stochastic Markov chain model to study allele progression across generations. In such a model, the allele frequencies in the next generation depend only on the frequencies in the current one.

We use this model to track a recessive allele …


S3e8: What’S So Cool About Cold-Water Corals?, Ron Lisnet, Rhian Waller Nov 2020

S3e8: What’S So Cool About Cold-Water Corals?, Ron Lisnet, Rhian Waller

The Maine Question

When people think of coral reefs, they might imagine snorkeling in warm Caribbean waters. But corals also live in the Gulf of Maine and in some of the most extreme environments on Earth, including the Arctic and Antarctic.

Rhian Waller, associate professor of marine sciences and a National Geographic Explorer, dives deep in near-freezing water around the world to learn about what she calls the rainforests of the ocean. She examines how climate change, fishing and oil exploration affect their ecology and reproduction. And she studies the effects that their altered life cycle might have on the marine ecosystem and …
