    Nyckelord :;

    Sammanfattning : During pregnancy, the fetus expresses both maternal and paternal antigens.

    Nyckelord :;

    Sammanfattning : The late effects in adulthood of nutrition during adolescence, childhood, infancy, and the fetal and embryonic stages of development have attracted much attention in research, but less so the time of development of the genome.

  4. 23. Egg carrying in the golden egg bug

    Författare :Minna Miettinen; Ingrid Ahnesjö; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hemiptera; Halvvingar; zoologi; Zoology;

    Sammanfattning : Females of the golden egg bug, Phyllomorpha laciniata Vill (Heteroptera, Coreidae), lay their eggs on the backs of male and female conspecifics. Eggs survive poorly in nature unless being carried by living conspecifics. The most likely evolutionary explanation to egg carrying is that individuals carry their own eggs. LÄS MER

  7. 25. On Sexual Imprinting in Humans

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Sexual Imprinting; Paraphilia; Fetishism; Sexual Preferences; Partner Preferences; Sexual Development; Ethology and behavioural ecology; Etologi och beteendeekologi; NATURAL SCIENCES; NATURVETENSKAP; etologi; Ethology;

    Sammanfattning : In this thesis I investigate whether human sexual preferences develop through sexual imprinting. Sexual imprinting is the acquisition of sexual preferences through non-rewarded experiences with parents and siblings during an early sensitive period and it is known to exist in many other animals.
