Polymorphic species Samenvattingen, Aantekeningen en Examens

Lecture notes from Imperial College London, Medical Biosciences BSc, 2nd year, genetics and genomics (GEN) module. By comparing the sequences of different species we can identify sequences that have been conserved over long periods of evolution and so are likely to have important biological functions. You will also see how the extent of such sequence conservation can be used to measure evolutionary relationships between the species. Similarly, when comparing sequences repeats within a single ...

MBG 2040 / MBG2040 QUIZ 2 ANSWERS Question 1 Inbred lines of self-fertilizing plants are typically homozygous for many genes and are often less vigorous than hybrid lines, this is referred to as: Inbreeding Depression Heterosis Hybrid vigour Allelism Question 2 Fatal Familial Insomnia is an inheritable prion disease caused by a mutation in the gene (PrPC) encoding the human prion protein (hPrP). The mutated allele (PrPSC) codes for a prion protein that replaces the typical α-h...
