PSYB30H3 Chapter Notes - Chapter 6: Human Genome, Heritability, Molecular Genetics
Document Summary
Genome: refers to the complete set of genes an organism possesses. Human genome contains 200000 and 25 000 genes. All these genes are located on 23 pairs of chromosomes. Each person inherits one set of each pair from mother and one set from father.

Misconceptions about heritability: it can be applied to a single individual- wrong it cant, it is constant- no if the environment change the heritability can change, it is a precise statistic- it is usually an estimate not precise. Behaviourial genetic methods: many methods to see individual differences like selective breeding, family studies, and twin studies, adoption studies. Selective breeding this occurs by identifying the dogs that possess the desired characteristic and having them mate only with other dogs that also possess the characteristic.
