Genetics is the study of heredity or inheritance. These resources will assist in the understanding of basic genetics.
The presence or absence of certain identifiers on the surface of red blood cells determine human blood type.
The genetic code is the information in DNA and RNA that determines amino acid sequences in protein synthesis.
A gene mutation is any change that occurs in the DNA. These changes can be beneficial to, have some effect on, or be seriously detrimental to an organism.
Chromosomes and Sex
What is the relationship between chromosomes and sex? Sex is determined by the presence or absence of certain chromosomes.
Sex-linked traits originate from genes found on sex chromosomes. Hemophilia is an example of a common sex-linked disorder that is an X-linked recessive trait.
Sex Chromosome Abnormalities
Sex chromosome abnormalities occur as a result of chromosome mutations brought on by mutagens or problems that occur during meiosis.
