Document Summary
Genotype: the genetic material an individual inherits. Phenotype: the observable expression of the genotype, including both body characteristics and behaviour. Environment: every aspect of an individual and his or her surroundings other than genes. The following are five relations that are fundamental in the development of every child: parent"s genotype-child"s genotype. Transmission of genetic material from parent to offspring. Dna codes for genes, and is packaged in chromosomes which are passed down. Genes make up only 2% of the human genome. The rest (used to be thought of as junk . Dna) turns out to play a supporting role in influencing genetic transmission by regulating the activity of protein-coding genes. Human heredity: 46 chromosomes, 23 pairs. Diversity and individuality: genes ensure humans will be similar at a species level and an individual level. Also guarantee differences at both levels: mutation: a change in a section of dna. Some are random, spontaneous errors, and others are caused by environmental factors.
