CH 14.1 Human Heredity. Human Chromosomes Each human chromosome consists of a single DNA molecule. Humans have 23 pairs of chromosomes, for a total of.
Sex-Linked Traits Most traits of the human genome are autosomal traits, which means the alleles for these traits are located on pairs 1 –22. Some traits.
Genetics Heredity passing down of traits or characteristics from parents to offspring Genetics study of heredity.

Chromosomes and Heredity. When Gregor Mendel formulated his laws of inheritance of traits, he did not know about meiosis or the existence of chromosomes.
Genes to Traits. Genes Gene- a piece of DNA that makes a certain protein – Example: Gene for tongue-rolling Allele- different forms of a gene – Example:
Non-Mendelian Genetics:
Sex-linked Traits. Sex Determination Sex chromosomes – determines the sex of an individual YY XX Males have X and Y Two kinds of gametes Female.
Sex-Linked Traits
Non-Mendelian Genetics: Genetics that don’t follow Mendel’s laws.
