Document Summary
Genotype: the genetic makeup of an organism - the unique set of genes that comprise that individual"s genetic code. Phenotype: the physical traits or behavioural characteristics that show genetic variation, such as eye colour, the shape and size of facial features, and even personality. Behavioural genomics: the study of dna and the ways in which specific genes are related to behaviour. When it comes to disorders such as alzheimer"s and schizophrenia, there is very little chance that any single gene could be responsible for them. Behavioural genetics typically involves comparing people of different levels of relatedness, such as parents and the offspring, siblings, and unrelated individuals, and measuring resemblances for a specific trait of interest. Monozygotic twins: come from a single ovum, which makes them genetically identical. Dizygotic twins: come from two separate eggs fertilized by two different sperm cells that share the same womb; these twins have approximately 50% of their genetics in common.
