WE talked about human genetics and how mutations can occur and how people can inherit something. We also talked about genotypes and enzymes

Human Inheritance-study of the inheritance of characteristics by children from parents
Genotypes-the genetic makeup of an organism
Phenotypes-an observable trait
Enzymes- a biological catalyst and is almost always a protein
Genetic Disorder- occur when a mutation affects your genes or chromosomes
Mutation- occurs when a DNA gene is damaged or changed in such a way as to alter the genetic message carried by that gene.
Genetics-the scientific study of genes and heredity—of how certain qualities or traits are passed from parents to offspring as a result of changes in DNA sequence
X Chromosome-one of the two sex chromosomes in humans
Y Chromosome-one of the two sex chromosomes in humans
Sex Linkedcharacteristics (or traits) that are influenced by genes carried on the sex chromosomes
