These patterns are called genes. Chromosomes Replication Chromosomes Humans have 23 pairs of chromosomes. 46 total chromosomes. Sex Chromosomes determine sex of individual. A genome is a complete compliment of genetic material from an individual.
Most cells are in interphase most of the time.
Interphase is when replication of the DNA occurs. This exchange occurs between the paternal version of the chromosme and the maternal version. The resulting chromosmes are a mosaic of alleles from both parents. Meiosis Mutations Germ line mutations versus Somatic Cell mutations. Germ line mutations are those that are passed on to the next generation through the sperm or eggs.
