- https://bio.libretexts.org/Courses/City_College_of_San_Francisco/Introduction_to_Genetics/06%3A_Sex_Chromosomes__Sex_Linkage/6.01%3A_IntroductionThis page details key learning objectives on autosomes versus sex chromosomes, sex-linkage exceptions to Mendel’s First Law, and inheritance patterns of sex-linked traits in Drosophila melanogaster. I...This page details key learning objectives on autosomes versus sex chromosomes, sex-linkage exceptions to Mendel’s First Law, and inheritance patterns of sex-linked traits in Drosophila melanogaster. It explains the role of the Y chromosome in sex determination, highlights Y-linked traits, and contrasts autosomal with sex-linked inheritance using human and turkey genetics examples, supported by visuals and a video resource.

It details how X-linked alleles are inherited with examp...This page explains the inheritance of sex chromosomes and autosomes, focusing on X-linked genes like the white gene in Drosophila melanogaster. It details how X-linked alleles are inherited with examples of mutations affecting eye color. The text emphasizes reciprocal crosses to identify sex-linkage, showcasing differences in offspring phenotypes. It also references Thomas Morgan's work, which established that genes reside on chromosomes.

It covers pseudo-autosomal regions that facilitate recombination between X and Y chromosomes, and illustrates how sex-linked genes diverge from Mendelian inheritance due to sex chromosome influence and dosage compensation. Examples from Drosophila and birds are provided.

It highlights the role of sex chromosomes in sex d...This page explains that diploid organisms have chromosome pairs, including autosomes and sex chromosomes, with humans having XY males and XX females. It highlights the role of sex chromosomes in sex determination and their unique behavior during meiosis based on whether an individual is homogametic or heterogametic. Additionally, it addresses misconceptions about the names of these chromosomes, clarifying that their names do not correspond to their physical shapes.
