1. 1. SubKluster: Novel method to bin scaffolds from cereal genomes into subgenomes using substring frequency analysis

   University essay from Lunds universitet/Examensarbeten i bioinformatik

   Author : Victor Kalbskopf; [2023]
   Keywords : Biology and Life Sciences;

   Abstract : The genome of the Belinda variety of the hexaploid oat (Avena sativa) has recently been sequenced and assembled. This project aims to improve the assembly by clustering the thousands of scaffolds into their three ancestral subgenomes using Principle Component Analysis (PCA) of kmer and repeat-element frequencies.

3. 2. Neanderthal genome sequencing : A genetic research study

   University essay from Uppsala universitet/Institutionen för arkeologi och antik historia

   Author : Susanna Uhr; [2023]
   Keywords : aDNA; genome sequencing; method progression; Neanderthals; modern humans; genetic divergence; interbreeding; aDNA; genom sekvensering; metodutveckling; Neandertalare; moderna människor; genetisk splittring; korsning;

   Abstract : The aim of this study is to provide information regarding the development of aDNA research. The essay also strives to distinguish eventual impact on previous and contemporary conceptions concerning Neanderthal and modern human genetic divergence and possible interbreeding between the two species.

4. 3. Evolutionary conservation analysis of sequence variants underlying ecological adaptation in Atlantic herring

   University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

   Author : Leyi Su; [2023]
   Keywords : Ecological adaptation; Evolutionary conservation; Atlantic herring;

   Abstract : The Atlantic herring (Clupea harengus) is a model organism for exploring the genetic basis of ecological adaptation on account of its large effective population size which greatly restrains the disturbance of genetic drift. In this project, I conducted an evolutionary conservation analysis of the Atlantic herring genome using conservation scores generated by phastCon, phyloP and GERP++ in order to study the sequence variants related to salinity or spawning-time adaptation in Atlantic herring.

5. 4. Sex-associated genomic variation in two ecotypes of Littorina saxatilis on the Swedish west coast

   University essay from Göteborgs universitet/Institutionen för marina vetenskaper

   Author : Amin Ghane; [2022-09-26]
   Keywords : Littorina saxatilis; Sex chromosomes; Sex determination systems; Sex-associated genomic region;

   Abstract : Sex, one of the most conspicuous characteristics of living organisms, has always been fascinating for biologists. The diversity of sex goes much beyond a simple distinction between males and females. Many organisms have more than two mating entities, and many species show some degree of hermaphroditism, at least in part of their life cycle. READ MORE

6. 5. Iterative full-genome phasing and imputation using neural networks

   University essay from Uppsala universitet/Människans evolution

   Author : Lotta Rydin; [2022]
   Keywords : Machine learning; Genotype data; U-Net; Convolutional neural networks;

   Abstract : In this project, a model based on a convolutional neural network have been developed with the aim of imputing missing genotype data. This model was based on an already existing autoencoder that was modified into a U-Net structure. The network was trained and used iteratively with the intention that the result would improve in each iteration. READ MORE
