  1. 1. Evaluating patterns of selection in reproductiveand digestive protein genes of seed beetles. : A comparative approach.

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Konstantinos Papachristos; [2021]
    Keywords : Seed beetles; Seminal fluid proteins; Female reproductive proteins; Digestive Proteins; Natural selection; Molecular evolution;

    Abstract : Seminal fluid proteins (SFPs) have been shown to affect the physiology,behaviour and immune responses of mated females in some species. Thisopen window for manipulation of female’s fitness allows the possibility forcomplex evolutionary dynamics between the SFPs and proteins of femalesthat would counter the effects of the former, the female reproductive proteins (FRPs).

  2. 2. Selfish, mobile genes in honeybee gut bacteria

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Aleksei Põlajev; [2018]
    Keywords : lactobacillus kunkeei; transposon; transposase; mobile genetic element; pseudogenized; gut flora; symbiont; reduced genome; åland; gotland;

    Abstract : Transposons are selfish, mobile genetic elements, moving within the genome. The transposase genemakes this possible, as it codes for the enzyme that catalyzes the movement. In the case of bacteria,they can also move horizontally between individual bacteria, and sometimes even between species. READ MORE

  3. 3. Probability calculations of orthologous genes

    University essay from Institutionen för kommunikation och information

    Author : Alice Lagervik Öster; [2005]
    Keywords : Phylogeny; Reconciliation; Orthology; Birth and Death process; Markov Chain Monte Carlo;

    Abstract : The aim of this thesis is to formulate and implement an algorithm that calculates the probability for two genes being orthologs, given a gene tree and a species tree. To do this, reconciliations between the gene tree and the species trees are used. READ MORE
