Hereditary Similarity and Variation Inheritance/heredity- the transmission of traits from one generation to the next Genetics- study of heredity and hereditary variation Offspring Acquire Genes from Parents by Inheriting Chromosomes Inheritance of Genes o Genes- coded information inherited from parents; segments of DNA Inherited information is passed on in the form of the gene’s specific sequence of nucleotides o Gametes- reproductive cells that transmit genes from one generation to the next. During fertilization, male and female gametes unite to pass on genes of both parents to offspring o Except for DNA of mitochondria and other organelles, DNA of eukaryotes is subdivided into chromosomes within the nucleus Each chromosome has a single long coiled DNA molecule o Locus- a gene’s specific location along the length of a chromosome Comparison of Asexual and Sexual Reproduction o Asexual reproduction- a single individual is the sole parent and passes copies of all its genes to its offspring
