BSCI105, Freshman Connection Fall 2010 Study Guide #11 I. Chromosomal Theory of Inheritance Vocabulary: Heredity Heritability Gene Allele Asexual Sexual Somatic Gametic Homologous Diploid Haploid Meiosis Key Concept 1: Different alleles of genes produce heritable variation that gets passed predictably from one generation to the next. Key Concept 2: Asexually reproducing organisms produce genetically identical offspring that exhibit little if any heritable variation within lineages. Key Concept 3: Sexually reproducing organisms have a lot of heritable variation and produce genetically novel offspring with a mix of parental traits.

Key Concept 5: Gametic cells (sex cells) are haploid cells with one copy off each chromosome. Key Concept 6: Gametic cells combine by fertilization to form a diploid offspring that shares half its chromosomes with each parent.
