Difference between autosomal and sex linked

The chromosomes, apart from the sex chromosomes , are known as autosomes of an organism. The number of chromosomes varies from one organism to others. In humans, there is a total of 46 chromosomes or in pair of Out of these, 2 are sex chromosome XX or XY , and 44 are autosomes. Mice have in all 40 chromosomes, out of which 38 are autosomes, and 2 are sex chromosomes. Abnormalities in the chromosomes autosomes or sex chromosomes results in the retardation in growth of an organism or delay in development.

Autosomal Traits - Advanced ( Read ) | Biology | CK Foundation

The chromosomes of the body are labeled as either autosomal or sex-linked based on which chromosomes they are. In a normal human, there are 22 pairs of autosomes and one pair of sex chromosomes. Become a Study. The difference between an autosomal chromosome disorder and a sex-linked chromosome disorder is the location of the gene or genes responsible for the Try it risk-free for 30 days.

8.4: Simple Inheritance

Every organism of a given species has a different set of alleles from every other individual of that species. Alleles are defined as "alternative forms of a given gene. Some characteristics are defined by a combination of several alleles with varying weight of expression. Alleles on autosomes are inherited from both parents, but alleles in mitochondrial DNA are inherited from the mother only. Twins are an example of organisms with identical alleles, so the answers claiming that all organisms have different alleles is false.

Genetic traits are characteristics that are encoded in DNA. Some genetic traits, like dimples, have a simple inheritance pattern like the traits that Gregor Mendel studied in pea plants. The way these traits are inherited by offspring from their parents is called simple inheritance. Simple or Mendelian inheritance refers to the inheritance of traits controlled by a single gene with two alleles, one of which may be completely dominant to the other. The pattern of inheritance of simple traits depends on whether the traits are controlled by genes on autosomes or by genes on sex chromosomes.
