Document Summary
Hard to find such a specific sample: lack of control: Only if they can gather data from both sets of parents: selective placement: characteristics or even are related to biological parents. Adoptive agencies match potential parents that match biological parents: homogeneity of adoptive homes: The lower variability of a variable, the less likely variables will correlate other thus, low correlation. Genotype vs. phenotype: genotype: set of genes inherited from parents, phenotype: observable and measurable expression, interacts with environment, examined by psychologists. Genetic transmission: ovum + sperm = zygote (23 pairs of chromosomes, 46 individual chromosomes thread-like structures in nucleus. Genes and dna: genetic information contained in deoxyribonucleic acid (dna, chemical bases: Adenine guanine; thymine and cytosine: order of bases determine organism and characteristics, based on protein production triggered by certain environment. Individual dominance: expression of one of the genes, usually the dominant over the recessive (e. g. Sex chromosomes: determine the person"s sex, xx = female, xy = male.
