Autosomal dominant pedigree chart. In Autosomal Dominance the chance of receiving and expressing a particular gene is 50% regardless of the sex of parent or child.

Crossing over occurs during meiosis I, and is the process where homologous chromosomes pair up with each other and exchange different segments of their genetic material to form recombinant chromosomes. In some species crossing over is essential for the normal segregation of chromosomes during meiosis. Crossing over also increases genetic variation, because due to the swapping of genetic material d

Schematic and relatively language-neutral karyogram of a human. Even at low magnification, it gives an overview of the human genome, with numbered chromosome pairs, its main changes during the cell cycle (top center), and the mitochondrial genome to scale (at bottom left). High magnification (of full size version) more clearly depicts a scale to the left of each chromosome pair that shows the leng

Schematic overview of the main steps involved in meiosis. Completely re-drawn and expanded from MajorEventsInMeiosis.svg to show more clearly the pairing of homologous chromosomes and crossing-over. 1: Chromosome duplication; 2: pairing of homologous chromosomes; 3: crossing-over; 4: first division – one of each duplicated chromosome per daughter; 5: second division – one of each chromosome per da

This pedigree has an autosomal dominant disorder. It is possible to tell the trait is dominant because it never skips a generation and there are no unaffected carriers. Affected children must have affected parents. When one parent possesses the trait and is heterozygous ( possessing a dominant and recessive allele) approximately half of the children will possess the dominant disorder.

This pedigree has a autosomal recessive disorder. It is possible to tell this order is recessive because it skips generations with none of generation 3 actually displaying the trait. When both parents display the disorder all of their kids have to display the disorder. But when only one parent displays the disorder all of the kids will be carriers but unaffected by the trait. It is possible to tell the trait is autosomal because it affects females and males equally.

Schematic and relatively language-neutral karyogram of a human. For each chromosome pair, the scale to the left shows the length in terms of million base pairs , and the scale to the right shows the designations of the bands and sub-bands . It shows dark and white regions as seen on G banding . Each row is vertically aligned at centromere level. The karyogram shows: - 22 homologous autosomal chromosome pairs - Both the female (XX) and male (XY) versions of the two sex chromosomes . For printing this image as a poster, the suggested size is approximately 47 x 79 cm. For more information and context, see Wikipedia:Karyotype#Human karyogram .
