Document Summary
Are we products of our genes (nature) or environment (nature) in which we are raised. Nature and nurture lie along a continuum, with some traits subject to greater influence from genes. Genes: basic unit of heredity; they are responsible for guiding the process of creating proteins that make up our physical structures and regulate development and physiological processes throughout the life span. Chromosomes: structures in the nucleus that are lined with all the genes an individual inherits. Dna: a molecule formed in a double-helix shape that contains four nucleotides: adenine, thymine, cytosine, guanine, Genes instruct cells how to behave, which type of molecule to produce, and when to produce them. Genotype: refers to the genetic makeup of an organism. Phenotype: consists of the observable characteristics, including physical structures and behaviors. Homozygous: two corresponding genes at a given location on a pair of chromosomes. Dd= dominant homozygous dd= dominant heterozygous dd= homozygous recessive.
