Answer:

Patterns of Inheritance

The phenotype of an individual is determined by his or her genotype. The genotype is determined by alleles that are received from the individual’s parents (one from Mom and one from Dad). These alleles control if a trait is “dominant” or “recessive”. Additionally, the location of the alleles in the genome determine if a trait is “autosomal” or “X-linked”. Traits are dominant if only one copy of the allele is required for expression of the trait. Traits are recessive if two copies of an allele are required for expression of the trait. X-linked traits are those controlled by an allele that is carried on the X chromosome, while autosomal traits are controlled by alleles located on any chromosome excluding the X or Y. Expression of X-linked traits depends on a number of factors including a dominant versus recessive allele, and the gender of the offspring.
