    Sammanfattning : Sex differences in the human body affect many different organs and tissues, some of them have an effect on the human brain and its development. In the developing nervous system, sex differences can bias the number or functionality of neurons, glial cells or synapses. As a result, neural networks might develop with a sex-specific bias.

    Sammanfattning : There is sex-bias in morbidity and mortality from infectious diseases. Infections kill more men than women and several studies have pointed out differences in the immune system as a reason. The sex hormones estrogen, progesterone and testosterone all shape the effect of the immune response on multiple levels. LÄS MER

  5. 4. Mutation and Diversity in Avian Sex Chromosomes

    Författare :Hannah Sundström; Hans Ellegren; David W. Burt; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; mutation rate; diversity; sex chromosomes; indels; male bias; selective sweep; effective population size; birds; Genetik; Clinical genetics; Klinisk genetik;

    Sammanfattning : Sex chromosomes are useful for the study of how factors such as mutation, selection, recombination and effective population size affect diversity and divergence.A comparison of gametologous introns in seven different bird species revealed a complete lack of diversity on the female-specific W chromosome.
