and define
Genes - individual units of heredity of all traits and are organized into long segments of DNA that occupy a specific location on a chromosome to determine a particular characteristic in an organism
Genotype
Genotype - specific genetic makeup of an individual, usually in form of DNA
Allele
1 of 2 or more alternative versions of a gene at a given position or locus on chromosome
Phenotype
the observed or outward characteristics of an individual
Homozygous

Mendelian laws of inheritance
Patterns occur because a single gene is defective and disorders that result are referred to as monogenic or mendelian
Monogenic disorders include:
Autosomal dominant
Autosomal recessive
X-linked dominant
X-linked recessive
Autosomal dominant inheritance disorder
occur when a single gene in the heterozygous state is capable of producing the phenotype
**mutant gene overshadows normal gene and person will show signs
Common types of genetic disorders that follow autosomal dominant pattern of inheritance include
neurofibromatosis, marfan syndrome, hungtington disease, achondroplasis, polycystic kidney disease
Autosomal recessive inheritance disorders
occur when 2 copies of the mutant gene in homozygous state are necessary to produce the phenotype
Common types of genetic disorders that follow autosomal recessive inheritance include
Cystic fibrosis
phenylketonuria
Tay-sachs disease
Sickle cell disease
X-linked inheritance disorders
associated with altered genes present on X chromosome
Male - will express conditon bc they have only one X
Females - have 2 X so either heterozygous or homo
X linked recessive inheritance
demonstrated recessive pattern of inheritance
More affected males than females bc all genes on male are X so it will be expressed
Females will need 2 abnormal X to exhibit otherwise are carriers

Chromosomal abnormalities
Do not follow striaghtforward pattern of inheritance
Occur due to random events during formation of reproductive cells
