Heredity: the transmission of traits from one generation to the next. Variation: offspring are not exact copies of parents/siblings. Genetics: scienti c study of heredity and hereditary variation. 13. 1 offspring acquire genes from parents by inheriting chromosomes. Genes: hereditary units, program the speci c traits that emerge as we develop from fertilized eggs, genetic program written in dna. Gametes: reproductive cells in animals and plants. Locus: speci c location of a gene along the length of a chromosome. Asexual reproduction: -only organisms that do this produce genetically identical offspring. Sunday, october 9, 2016: clones wow, variations happen by mutation. Sexual reproductions: 2 parents give rise to offspring that have unique combos of genes inherited from the 2 parents, vary genetically from siblings and parents. 13. 2 fertilization and meiosis alternate in sexual life cycles. Life cycle: generation-to-generation sequence of stages in the reproductive history of an organism from conception to its own offspring.
