Document Summary
Behaviour: our genetic endowment combined with environmental factors. Nature and nurture must work together to determine the outcome of behaviour an offspring will display. Gregor mendel = father of modern genetics. Heredity: passing on specific organic factors from one generation to the next, not a blending of parents characteristics. Can be recessive or dominant characteristics (visible or not) Genotype: the specific genetic makeup of an individual, always present from conception and never change. Phenotype: the observable characteristics produced by genetic endowment, can be affected by other genes and by the environment. Chromosome: tightly coiled molecule of dna that is partly covered by protein. Every cell in the human body contains 46 chromosomes except for sex cells which have. At conception the egg and sperm cell (which both have 23) combine to form a zygote (46 chromosomes. Alleles: alternative form of a gene that produce different characteristics.
