Document Summary
External factors can affect the switching on and off of genes. Range of reaction: all of the phenotypes that could theoretically result from a given genotype, given all the environments in which it could survive and develop. A child with a given genotype would probably develop quite differently in a loving, supportive family compared with growing up in an alienated, abusive family the child actively creates and explores the environment in which s/he lives. Genetic structures: most of the dna is in the nucleus, the rest of the dna in the cell is in the mitochondria, dna in the mitochondria is maternal (from mother only) Chromosomes and the karyotype (autosomes) chromosome: carries the genetic information of the body information is arranged in a linear sequence. Most of our cells contain 46 chromosomes 23 pairs (1 set from mother, 1 set from father)
